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

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.

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.

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

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.

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.

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.

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

These Buna-N seals are reinforced with cotton thread for strength.

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

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

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

Made from glass-filled nylon for excellent wear resistance and strength.

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

Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O-rings. They also require less compression to make a seal, so they offer a longer service life.

These hard O-rings offer better wear resistance than standard Buna-N O-rings.

Made of silver-plated 321 stainless steel, these O-rings can handle extreme pressure up to 11,000 psi. They resist grease, hydraulic oils, mineral oil, motor oil, and synthetic lubricants.

Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O-rings. They also require less compression to make a seal, so they offer a longer service life.

Softer than standard Viton® fluoroelastomer O-rings, these offer a better seal in low-pressure applications.

All of these O-rings meet MIL-R-83248C.

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection. They meet MIL-R-83248.

These temperature- and chemical-resistant O-rings prevent leaks in tube fittings that have a straight-thread connection, also known as O-ring boss fittings.

Unlike silicone, the Viton® fluoroelastomer core will continue to ward of chemicals should the FEP casing wear away.

Able to bounce back after repeated compression, these Kalrez 7075 O-rings last longer than other Kalrez O-rings when exposed to repeated heating/cooling cycles.

Also known as Boss O-rings, these Kalrez 4079 O-rings are for use in tube fittings with a straight-thread connection. They’re inherently softer and more compressible than PTFE O-rings with comparable chemical resistance.

These silicone O-rings withstand temperatures up to 400° F or 450° F.

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection.

These O-rings also resist ethanol and ethylene glycol.

Made of FDA-listed material for use with food and beverage.

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection.

Made of Buna-N, these backup rings resist grease, petroleum fluids, and motor oil.

The X shape of this cord stock provides four points of contact for a better seal in dynamic applications than round profile. It also requires less compression to make a seal, so it offers a longer service life.

This square-profile cord stock has flat edges on all four sides, which creates a better seal than round profile in static applications, such as hose, pipe, and faucet connections.

Harder than standard Viton® fluoroelastomer cord stock for better wear resistance.

The brown color of this cord stock makes it easy to identify.

More chemical resistant than standard Viton® fluoroelastomer, this cord stock is made of Grade ETP Viton® fluoroelastomer. It resists harsh chemicals, such as calcium hydroxide, methyl ethyl ketone (MEK), and nitric and phosphoric acids.

This cord stock is softer and creates a better seal than standard silicone cord stock in low-pressure applications up to 400° F.

In addition to water and steam, this EPDM cord stock resists diluted salt solutions, ethanol, and isopropyl alcohol.
