Rod and Piston Seals

Buna-N U-Cup Seals

These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. Also known as lip seals, U-cups have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing.

High-Pressure Leather U-Cup Seals

Rated for pressure up to 10,000 psi, these leather U-cups handle over 80 times more pressure than our Buna-N U-cups.

High-Speed Piston Seals

PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.

High-Stability
High-Speed Piston Seals

A square O-ring prevents these piston seals from rocking in the groove.

Piston Seals for O-Ring Grooves

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

High-Pressure Piston Seals

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

Rod Seals

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

Rod Seals for O-Ring Grooves

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

High-Speed Rod Seals

The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.

High-Pressure Hydraulic
Cylinder Buffering Seals

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

High-Speed Hydraulic
Cylinder Buffering Seals

PTFE gives these seals a slippery surface that facilitates rod speeds over seven times faster than our other buffering seals. They're rated for pressure up to 5,000 psi.

Air-Powered Cylinder
Cushioning Seals

For use in air-powered cylinders, these seals prevent the piston from slamming against the cylinder body to minimize wear and noise.

Rod Wipers

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

Rod-Sealing Wipers

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

Cylinder-Sealing Rod Wipers

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

High-Speed Rod Wipers

Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.

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.

Wear Rings

High-Speed Wear Rings

Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.

Wear Ring Stock

Cut this stock to make wear rings that fit any rod or bore diameter.

Rotary Shaft Seals

Bore-Sealing Spring-Loaded
Rotary Shaft Seals with Wiper Lip

Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.

Spring-Loaded Rotary
Shaft Seals with Wiper Lip

These seals have a metal case that creates a tight seal when mating with smooth surfaces.

Spring-Loaded Rotary Shaft Seals

Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.

Spring-Loaded Rotary Shaft
Seals for Misaligned Shafts

Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". They're also known as clipper seals.

Rotary Shaft Seals for Grease

Also known as grease seals, these are designed to retain thick lubricant at low pressure. They have a light grip on the shaft that creates less friction than spring-loaded seals.

Split Rotary Shaft Seals

Swap out old seals without disassembling components—these seals come split for easy installation. They're also known as clipper seals.

Shaft-Mounted Rotary Seals

Made from Buna-N for excellent resistance to oil and grease.

Heavy Duty Shaft-Mounted
Rotary Seals

These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F.

Stackable V-Ring Packing Seals

High-Pressure Leather
Stackable V-Ring Packing Seals

These leather V-ring packing seals handle over twice the pressure as PTFE. Leather is tough, pliable, and wear resistant, so it flexes to fit uneven surfaces and fill voids.

PTFE Stackable
V-Ring Packing Seals

PTFE has excellent chemical resistance and withstands a wide temperature range of -110° F to 500° F.
