About O-Rings

O-Ring-Loaded U-Cup Seals

Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals.

High-Stability O-Ring-Loaded U-Cup Seals

Also known as Type B seals, these U-cups are wider than our other O-ring-loaded U-cup seals for better stability and fit in wider grooves.

Rod Seals

These seals have a beveled lip that optimizes contact against the rod, while a secondary lip keeps the seal stable.

Head Seals

Replace the standard O-ring/backup ring combination with a more reliable alternative—these head seals resist twisting and remain stable even in applications with fluctuating pressure.

High-Pressure Hydraulic Cylinder Buffering Seals

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our buffering seals.

Rod-Sealing Wipers

A two-lip design means that these wipers also function as a rod seal.

Rod Wipers

These rod wipers are also known as U-type wipers.

Cylinder-Sealing Rod Wipers

These wipers seal against the cylinder housing to prevent contaminants from entering between the outside edge and the housing.

Rod Wipers for Open Grooves

Replace wipers in open-groove cylinders—these wipers have an integral steel case so they press fit into the groove around the rod.

Oil- and Abrasion-Resistant Polyurethane O-Rings

More abrasion resistant than Buna-N O-rings, these also resist mineral oil and motor oil.

Ultra-Strength Oil- and
Abrasion-Resistant Polyurethane O-Rings

These O-rings are harder and stronger than standard polyurethane O-rings to handle high-pressure applications.

Oil- and Abrasion-Resistant Polyurethane O-Rings
for Tube Fittings with Straight-Thread Connection

Commonly called Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection.

Water-Resistant Rubber Flange-Mount Seals

The foam core makes these vinyl rubber seals firmer and more durable than hollow seals. They also resist salts and detergents.

Rod Seal Kits

Replace all the seals on the rod end of a hydraulic cylinder.

Drum Patches

Patch drum leaks to prevent their contents from spilling, even if they hold messy and dangerous substances, such as oil, chemicals, and solvents.

Abrasion-Resistant Rubber Balls

Food Industry Abrasion-Resistant
Polyurethane Rubber Balls

Safely use these balls in food and pharmaceutical environments to clean screens in vibrating sifters or to act as a seal in pumps and check valves.

Abrasion-Resistant Polyurethane Rubber Balls

Use these polyurethane balls as seals in pumps and check valves or let them bounce inside of vibrating sifters for an effective screen cleaner. They are made of polyurethane, which combines the shock absorbing qualities of rubber with the strength of plastic.
