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.

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

These seals are commonly used in well, sump, and displacement pumps.

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.

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

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

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.

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

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

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

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

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

Made of Buna-N, these O-rings resist grease, hydraulic oil, and motor oil—plus mild chemicals and water.

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

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

These O-rings have eight points of contact for a better seal in dynamic applications than X-profile O-rings, plus they have eight grooves that hold lubricant to reduce friction and wear for a longer service life.

These Buna-N O-rings are made of FDA-listed material for use with food and beverage.

If these O-rings deteriorate, they can be picked up by metal detection systems.

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

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.

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

Because one black O-ring looks just like another, these O-rings are brown for easy identification.

These are the highest purity chemical-resistant O-rings we offer. They are made and bagged in an ISO Class 7 and Fed. Spec. Class 10,000 clean room, plus they’re USP VI certified; not for use in medical applications.

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

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.

Flexible even at temperatures as low as -60° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol.

When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements.

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.

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.

Made of FDA-listed material for use with food and beverage, this cord stock resists animal and vegetable oils, citric acid, sodium bicarbonate, and grease.

This cord stock resists benzene, boric acid, ethylene glycol, and isopropyl alcohol.

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.

Use this cord stock to create O-rings for high-temperature applications up to 400° F.

Create round-profile O-rings for sealing applications near ovens and other hot areas in your food plant.

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

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.
