Sealing is essential for every hydraulic system as it prevents fluid leakage and improves the performance of the system. We offer an extensive range of replacement hydraulic, pneumatic and oil seals to keep your machinery moving.

View our seal ranges by application type:

  • U-Cup Hydraulic Seals

    Also know as lip seals or packing cups, U-Cup seals are used in projects that include hydraulic pressure including lifts, presses and pistons and rods. They are best in low-pressure applications.

  • Oil Seals

    Used to prevent water, dirt, and unwanted substances from entering equipment. Installed between the shaft and the housing, they protect ball bearings inside, keeping the mechanics running smoothly.

  • Pneumatic Seals

    The EU Pneumatic seal is a self retaining rod wiper seal for pneumatic cylinder piston rods. It simultaneously operates the three functions of wiping, sealing and fixing, increasing efficiency.

What are hydraulic seals?

Hydraulic seals are generally relatively soft, non-metallic rings captured in groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications.

Hydraulic and pneumatic seals are specifically designed for the requirements and environment they will be used in, with factors such as cylinder working pressure, cylinder speed, operating temperature, working medium and the intended application taken into consideration. 

Learn about the common hydraulic seal types, their variations, what they are made from, and more.

What are hydraulic seals used for?

Hydraulic seals are vital in machinery, their use is critical in providing a way for fluid power to be converted to linear motion. The most commonly used material is acrylonitrile or nitrile butadiene rubber (NBR), and they are used in hydraulic machinery, such as motors, pumps, jacks, brakes, lifts, and much more.

Some of the common industries that utilises hydraulic seals to limit or eliminate fluid leakage includes aerospace manufacturing, automotive manufacturing, agriculture, defence contracting and nuclear power.
