The A–Z of Hydraulic Seals

Whether you're a hydraulic pro or just found out seals aren't only at the zoo. Here is my A-to-Z guide to breaks down everything you never knew you needed or wanted to know about hydraulic seals—what they do, what they're made of, and why your equipment throws a tantrum without them.

A – Application

Choosing the right seal starts with understanding your Application—pressure, temperature, motion, and fluid compatibility all matter. Using the wrong seal? That’s like trying to fix a leak with chewing gum—temporary at best and definitely not the right application!

B – Breakdown Prevention

Seals play a major role in preventing breakdowns by keeping contaminants out and hydraulic fluid in. Regular maintenance is key to make sure your Seals are up to par.

C – Compatibility

Material and design must be compatible with the fluid and system conditions to prevent early failure.

D – Dynamic Seals

These seals manage movement, these include piston seals, rod seals, wiper seals and wear rings are constantly subjected to wear and friction.

E – Extrusion

A common seal failure caused when pressure forces the seal material into gaps between metal components—watch those tolerances!

F – Friction

The right Fit is important as well as having the proper seal design to minimize friction, helping components move smoothly and efficiently without heat buildup.

G – Gaskets

Well these are kind of different but they still count, gaskets are static seals used in hydraulic systems to prevent leaks between stationary parts.

H – Hardness

The Durometer—or hardness—of a seal plays a big role in how flexible it is and how well it holds up over time. Think of it like Goldilocks: too soft and it wears out fast, too hard and it won’t seal properly. You need it JUUUST right—because in hydraulics, leaks aren’t cute, and there's no fairy tale ending for blown seals

I – Installation

Incorrect Installation is one of the top reasons seals call it quits early. Let be real nothing says “I give up” like being shoved in backwards and expected to perform miracles.

J – Joint Integrity

Seals are the behind-the-scenes MVPs, keeping hydraulic Joints snug, systems leak-free, and everything running so smoothly you'd think the laws of physics were taking the day off.

K – Kits

Because of the important of seals within your hydraulic systems, there is more likely than not a Seal kits available that offers all the necessary components for servicing cylinders or pumps, great for maintenance and repair work.

L – Leakage

The #1 killer of hydraulics systems. GOOD SEALS = zero leakage = Continued productivity of your hydraulic system while maintaining safety.

M – Materials

Depends where and what the seal is being used for, the material is very important. From nitrile to Viton to PTFE, seal materials determine heat resistance, chemical resistance, and lifespan.

N – Nitrile (NBR)

A widely used sealing material due to its affordability, flexibility, and resistance to oil-based fluids.

O – O-Rings

The KING of the seals. The most common type of seal. O-rings are extremely versatile and are used in both static and dynamic applications.

P – Piston Seals

Piston seals keep pressure on one side of the piston where it needs to be and prevent fluid from crossing over to the other chamber.

Q – Quality Control

Quality of seals is important as not all are made with the same standards. We source seals from suppliers with strong quality control. A poor seal can mean major downtime and can be hazardous to your work environment.

R – Rod Seals

No one wants a fountain of hydraulic fluid flying out of the top of your cylinder. As mentions these are located in the cylinder head, rod seals keep fluid from leaking out as the rod moves in and out.

S – Static Seals

The glue between stationary surfaces, these seals don’t move and are used in joints, flanges, and covers to create a leak-proof seal.

T – Temperature Resistance

Hydraulic systems can get hot! Seals must maintain performance across a wide temperature range and many factors are taken into account to make sure this happens.

U – U-Cups

One the popular kids in the yard, this seal provides a tight, self-energizing seal under pressure—used for both rod and piston applications.

V – Viton

Just like a true Albertan, this material can handle all the weather curveballs we throw its way—whether its rain, snow, or desert heat, it’s unfazed. A premium sealing material renowned for its chemical and temperature resistance, it’s built tough to perform flawlessly in the harshest environments.

W – Wipers (Scrapers)

The janitor of the seals. These remove dirt and debris from the rod before it re-enters the cylinder—essential for seal protection.

X – eXtruded Seals

UH OH!! This isn’t supposed to be like that. Watch for extrusion damage on seals under high pressure—back-up rings can help prevent this.

Y – Yield Point

Again, regular maintenance is important, as well as making sure you are using your hydraulic systems correctly. Materials used for sealing must stay flexible within the system's yield point, exceeding this leads to deformation and failure.

Z – Zero Downtime

At Northland Air Hydraulics Ltd., we’re here to help you seal the deal, literally. From making sure the seals used are the right ones for the job to keeping them in tip-top shape, our mission is to keep your hydraulics flowing, your seals happy, and your downtime so close to ZERO it might as well be a rounding error.

How Often Should Hydraulic Equipment Be Sent in for Maintenance?

ENERPAC SIMPLEX SPX POWERTEAM HYTORC

Hydraulic equipment powers critical operations across industries such as construction, energy, and manufacturing. To maintain peak performance, prevent costly downtime, and ensure safety, regular maintenance is essential. While specific intervals vary by equipment type and usage, a general maintenance schedule is widely recommended by industry experts and manufacturers-including Enerpac, a leading provider of hydraulic tools.

It's always best to base maintenance procedures on manufacturers guidelines but these are some general suggestions to consider.

Recommended Maintenance Schedule

• Daily or Weekly Checks: Operators should perform routine inspections of fluid levels, look for leaks, and monitor system temperatures. These quick checks help identify small issues before they escalate, improving safety and reducing unplanned downtime.

• Monthly Preventative Maintenance: Monthly tasks include inspecting hoses, filters, and connections, and assessing hydraulic fluid condition. Contaminated or degraded fluid reduces system efficiency and accelerates wear. Changing hydraulic oil every 1,000 hours or as specified by the manufacturer is a common guideline.

• Quarterly or Biannual Service: Every 3 to 6 months, a more thorough service should be performed, including replacing hydraulic fluid and filters, checking pressure settings, and inspecting actuators and seals. Using genuine parts and qualified technicians-such as those recommended by Enerpac-helps maintain system integrity.

• Annual Full Inspection: For high pressure equipment, a full-system inspection or overhaul is advised annually or according to manufacturer-specified hours. This helps identify wear and fatigue in critical components, ensuring safety and operational efficiency.

Why Regular Maintenance Matters

Hydraulic systems operate under high pressure, and failures can cause leaks, bursts, or hazardous movements, posing serious safety risks. Proper maintenance reduces these risks and keeps workers safe. Moreover, well-maintained equipment runs more efficiently, minimizing fuel or energy consumption and preventing costly production delays.

Industry and Manufacturer Recommendations

Industry standards such as ISO 9001, ISO 4413, ANSI/HI 9.6.5, and OSHA regulations all emphasize the importance of systematic, proactive maintenance programs. Following manufacturer guidelines-like those provided by Enerpac-ensures compliance with safety and quality requirements and helps extend equipment lifespan.

Hydraulics: The Pint-sized powerhouse of the lifting world

Go! Go! Gadget hydraulics. Inspector Gadget probably wished he has this for one of his gadgets. Probably would have been one of his most effective tools and could have saved him a lot of trouble.

Did I make hydraulics sound a little more exciting yet? I mean, the word itself feels like it belongs in a dusty old engineering textbook. Come on! Science can be fun… The power of what some fluid can do with little to no effort is pretty cool in a Dorky way. Take for instance something the size of a can of pop can lift your car with a push of a button. The roads and bridged you drive on, thanks hydraulics. All those amazon packages you get, it’s ok we all know you enjoy amazon just the rest of us, hydraulics definitely had a part in getting those to you. But let talk specifically lifting.

So… What Is Hydraulic Lifting?
As I mentions above, imagine you had the strength of an elephant packed into a soda can. That’s basically what a hydraulic system is doing—using fluid (in most cases this is oil) to create massive amounts of force. You push a little fluid here, and badabing!!—something huge moves over there. Mr. Clean has his little ol’ magic eraser but the rest of us have the power of itty bitty systems that essentially can move mountains.

Ok, let’s get a little nerdier. All this is because of Pascal’s Law, which sounds like something you faintly remember from physics class in high school when you mastered the I’m paying attention but not actually paying attention skill of life, but it’s actually mind blowing: “Pressure applied to a confined fluid is transmitted undiminished in all directions.” Translation: Put a little juice in it and there she goes.

It’s Basically Magic, only not hidden secrets like Houdini?
Let’s say you press on a small piston the size of a bottle cap. That push moves fluid into a much bigger piston—let’s say the size of a dinner plate. Because the fluid pressure stays the same, the big piston moves with way more force. Congratulations! You just became the next Mr. Strongman and lifted a car with your pinky (well, sort of).

It’s like mechanical alchemy. Work smart not hard. Even forklifts, garbage trucks, and that ride at that amusement part you thought would be a good idea to go on that almost made you remember what you had for breakfast rely on hydraulic lifting.
Superpowers in the everyday life

Hydraulics are hiding in plain sight, flexing their muscles in places we barely notice:

 Elevators: That smooth glide up to the 15th floor? Yup, hydraulic lift.
 Backhoes and Excavators: Basically giant robot arms running on fluid power.
Car Brakes: Hydraulics give you the stopping power to make sudden red-light halts slightly less terrifying.

The Real Fascination?

It so simple! A couple tubes here, some fluid there, and boom—you’re lifting 500 tons. I like to think this is engineering at its finest. It’s clean, it’s quiet (this doesn’t included that powerful pump that some have that would make Tim the tool man jealous with what power it has) and ridiculously strong. And there's just something so satisfying about seeing a massive object float upwards with no visible effort.

So next time you see that worker up in the air fixing a streetlight, or a tow truck pulling that car out of a ditch after a crazy snow storm and lifting it onto the deck of his truck, give a little round of applause to hydraulics. They may not wear capes—but they may just be one of the closest thing to having that super power always wanted.

Mechanical vs. Hydraulic Systems: What’s the Deal? What Would Work Best for You?

When it comes to moving things, lifting loads, or powering machines, both mechanical and hydraulic systems can get the job done — but they go about it in very different (and honestly, pretty cool) ways.

Let’s break it down.

🛠️ Mechanical Systems: Classic Simplicity That Still Delivers

Think old-school — a system that’s been around forever and is still going strong. Mechanical systems are all about using basic movements to achieve a goal. You push here, something turns there — simple, reliable, and tactile. Gears, levers, pulleys, belts, and shafts do the work without the need for fluid, electronics, or complexity.

These systems are so solid that if it ain’t broke, don’t fix it. They were used back in the day, they’re used now, and your great-grandkids will probably still be using them.

✅ Pros:

• Simple designs and easy to operate

• Easy to diagnose and fix problems

• No fluid, seals, or leaks to worry about

⚠️ Cons:

• Friction and wear can limit lifespan

• Not as precise for fine control

• May not be ideal for tight-space or high-load applications

💧 Hydraulic Systems: Power in Fluid Form

More power! That’s the magic of hydraulics. With the help of fluid — usually oil — you can generate far more force than a mechanical setup of the same size. Pressurized fluid flows through pumps, valves, and hoses to deliver smooth, powerful, and precise motion.

If you need accuracy, strength, and control — especially in tight or high-demand environments — hydraulics is the way to go.

✅ Pros:

• High power-to-size ratio

• Smooth, accurate, and consistent movement

• Self-lubricating thanks to the fluid

⚠️ Cons:

• Prone to leaks without regular maintenance

• More complex (pumps, fluid lines, seals, fittings)

• Fluid contamination can impact performance

⚖️ So, What’s the Bottom Line?

• Use mechanical systems when you need something simple, quick, and reliable — especially for general tasks with fewer precision demands.

• Use hydraulic systems when you need strength, control, and accuracy — particularly in tight spaces or for heavy-duty applications.

Both systems have their place. It’s all about choosing the right one for your task — and doing it safely and efficiently.

Whether you're after the simplicity of a mechanical system or the muscle of a hydraulic one, Northland Air HydraulicsLtd. is your go-to source. 

We offer top-tier products, expert advice, and personalized support to help you choose the right system for your needs. With decades of experience, a full-service shop, and a reputation for reliability, we’re here to help you power up — the right way.

Hydraulic Tools: What Are They and How Do They Work?

Hydraulic tools are an essential part of many industries, from construction to manufacturing to automotive repair. These tools use the principles of fluid dynamics to perform various tasks, from lifting heavy objects to drilling through tough materials. But what exactly is a hydraulic tool, and how does it work? In this blog post, we'll answer these questions and more.

What Is a Hydraulic Tool?

A hydraulic tool is a machine that uses fluid pressure to perform work. The most common type of hydraulic tool is a hydraulic cylinder, which uses hydraulic fluid to create force and move a piston or plunger. Other hydraulic tools include hydraulic pumps, valves, and motors, all of which work together to create a fluid-based power system.

How Does a Hydraulic Tool Work?

At its most basic level, a hydraulic tool works by using a liquid (usually hydraulic oil) to transmit force from one place to another. The liquid is typically held in a closed system, consisting of a pump, hoses or tubing, valves, and the hydraulic tool itself.

When the pump is activated, it pressurizes the hydraulic fluid and sends it through the hoses or tubing to the tool. Once it reaches the tool, the fluid pushes against a piston or plunger, creating force that is used to perform work. The force created by the hydraulic tool is proportional to the amount of pressure created by the pump and the size of the piston or plunger.

The fluid is then returned to the pump to complete the cycle. This closed system allows hydraulic tools to operate continuously and efficiently, with minimal waste or loss of energy.

What Are the Advantages of Hydraulic Tools?

Hydraulic tools offer several advantages over other types of tools. First, they can create immense force and torque with relatively small pumps and motors, making them ideal for heavy-duty tasks. Second, hydraulic tools are more versatile than other types of tools, as they can be easily adapted to perform different tasks by changing out the tool head or attachment.

Finally, hydraulic tools are generally more reliable and durable than other types of tools, as they have fewer moving parts and can operate continuously without overheating. This makes them a popular choice for industries where downtime and equipment failure can result in significant financial losses.

Conclusion

In summary, hydraulic tools are powerful machines that use hydraulic fluid to create force and perform work. They offer several advantages over other types of tools, including versatility, durability, and reliability. If you're considering investing in hydraulic tools for your business, it's important to understand how they work and how they can benefit your operations. With the right equipment and maintenance, hydraulic tools can help you tackle even the toughest jobs with ease.

RTJ Flange (Ring Type Joint): Definition, Applications, and Repair

What is an RTJ Flange (Ring Type Joint)?

The RTJ flange (Ring Type Joint) is designed for high-pressure and/or high-temperature pipeline applications. This makes them the required standard in API specification flanges.
Applications include oil field valves, pipework assemblies, and high integrity pressure vessel joints.

Like other flanges, they use a gasket under compression to create a secure joint. But an RTJ flange differs from the more common flat and raised face flange in several ways:

• The gasket used is a steel ring – instead of the flat composite material type.

• An RTJ flange has a groove machined into the flange surface to accept the gasket.

• When the gasket deforms it creates a metal-to-metal seal.

• Under compression, the softer metal of the gasket flows into the microfine structure of the harder flange material.

• The raised faces of connected and tightened RTJ flanges may be in contact with each other. When this happens, the compressed gasket will not bear any extra load. The benefit is the integrity of the joint will be protected from over-tightening, vibration, and movement.

RTJ Flange Materials

• Stainless Steel

• Duplex & Super Duplex Steel

• Carbon Steel

• Low-Temperature Carbon Steel

• Alloy Steel

• Copper Alloy

• Nickel Alloy

RTJ Flange Gasket Materials
Select the gasket to suit the service conditions. It is always recommended that the gasket material is softer than the mating flange.

RTJ gaskets are available in materials that include, Soft Iron, Low Carbon Steel, Stainless Steel, Titanium, Hastelloy, and Super Duplex.

Types of RTJ Gaskets

Style R Gasket Rings

This is the original and basic type of RTJ gasket design for the high temperatures and pressures experienced in the oil and gas and petrochemical industries. In accordance with ASME B16.5 they are intended for pressure ratings up to 5,000 psi. R type gaskets are available with an oval or octagonal cross-section.

Style RX Gasket Rings

The Style RX is an adaptation of the standard Style R. The RX is designed to fit the same groove design as a standard Style R – making the joints interchangeable. RX rings use a pressure-energized effect that improves the efficiency of the seal as the internal pressure increases. Pressure passage holes are included in sizes RX 82 through to RX 91, which allows the pressure to be equalized.

Style BX

BX Ring Type Joints gaskets are designed for the highest pressurized systems from 5000 up to 20,000 psi. The design allows face to face contact of the flange faces – which means the gasket is fully trapped on both the inner and outer diameters. These also feature a pressure balance hole to relieve air pressure trapped within the grooves. They cannot be interchanged with the other two types.

Machining RTJ Flange Grooves

The sealing face on a ring-type flange is not spiral serrated as used you see on a raised face flange. Instead, the sealing surfaces are smooth and mirror-like. These need to be finished to 63 microinches and should be free from ridges, scratches, or chatter marks.

When machining ring-type joint grooves onsite, the resulting dimensions need to be as described in the standard ASME B16.5.

This can be carried out on-site using a flange facing machine. Machines from Enerpac do not require any optional extras to complete RTJ machining. These are commonly used to machine RTJ flanges.

Flange facing machines for RTJ machining splits into two capabilities to create the 23° seal faces. Machines with auto-axial feed use an in-built axial gearbox, whereas others use a ‘kick-feed’ for the axial feed. (Both types are also capable of manual feed by the operator).

• Auto-axial feed type – Ideal for RTJ machining. Examples with this feature include the MM1000i, MM1500i, MM2000i, MM600e models.

• Striker kick feed type– where the axial feed is achieved by a striker or manually by tye operator. Examples include the MM300E, MM305i, and MM610i.
