For a better seal in low-pressure applications, such as hydraulic return lines and oil drain plugs, these O-rings are softer than standard Buna-N O-rings.

When you need an O-ring that’s not an industry standard size, we can make one to fit your requirements. These resist grease, hydraulic oils, and motor oil.

A slick surface treatment makes these O-rings easy to seat without tearing or rolling. The lack of friction also helps create a long-lasting seal in dynamic applications, no lubrication required.

With four points of contact for a strong seal, these X-profile O-rings are often used in dynamic applications, such as on pistons and rotating shafts. Also known as Quattro seals and X-rings, they resist rolling and twisting better than round- and square-profile O-rings.

If these O-rings deteriorate, they’ll be picked up by metal- and X-ray-detection systems.

These Buna-N O-rings are made and bagged in an ISO Class 7 (Fed. Std. 10,000) clean room.

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

A step up from Buna-N, these HNBR O-rings contain extra hydrogen to better resist chemicals, weather, and abrasion.

Tested to meet ASTM E595, a standard used by NASA, these O-rings give off almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

Tested to meet ASTM E595, a standard used by NASA, these O-rings give off almost no volatile emissions that could damage sensitive electronics, even in a vacuum. They’re softer than standard Viton®, so they better conform to irregular surfaces.

Heat treated, cleaned, and double-bagged in an ISO Class 5 clean room, these O-rings come ready for use in high-vacuum systems.

With flat edges on all four sides, these square-profile O-rings cover more surface than round-profile O-rings for a better seal in static applications, such as hose, pipe, and faucet connections.

Made and bagged in an ISO Class 7 clean room, these O-rings won’t shed particles.

Made of Viton® fluoroelastomer, these O-rings meet MIL-R-83248 standards. They stay strong when used with chemicals such as benzene, butyl alcohol, and ethylene glycol.

Made for demanding applications, these O-rings hold up to constant motion, repeated compression, and extreme temperatures. They’re often used for centrifugal pumps and high-pressure hydraulic valves in chemical processing systems.

Our most chemical-resistant Viton® fluoroelastomer O-rings. Made of Viton® ETP, these O-rings stay strong when used with harsh chemicals including acetone, MEK, and sodium hydroxide. They also keep their elasticity and shape under constant motion in steam and heat.

Made of Kalrez 4079, these O-rings combine the chemical resistance of PTFE with the springy softness of Viton® fluoroelastomer.

Made for demanding applications, these Kalrez 7075 O-rings hold their shape even after repeated rubbing or compression. More durable than Kalrez 4079 O-rings, they also have higher tensile strength and heat resistance.

Made from PTFE, these O-rings withstand extreme temperatures and harsh chemicals such as acetone, fluorinated solvents, and ethanol.

Seal lines and valves in HVAC systems, freezers, and other cold applications exposed to chemicals. Made with an FEP casing, these O-rings are protected against chemicals such as methanol and boric acid.

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

Get the same chemical and heat resistance as Kalrez 4079 without the brand name. Even at 600° F, these FFKM O-rings resist a wide range of chemicals, including acetone, methyl ethyl ketone (MEK), potassium hydroxide, and most acids.

Made of silicone, these O-rings can withstand temperatures up to 400° F or higher. They're FDA compliant for direct contact with food, so they're often used on hot food lines.

When you need a silicone O-ring that’s not an industry standard size, we can make one to fit your requirements. These O-rings withstand temperatures up to 400° F.

Made and bagged in an ISO Class 7 (Fed. Std. Class 10,000) clean room, these are the highest purity high-temperature O-rings we offer.

Trusted for their quality and consistency, these E0603 EPDM O-rings resist water, steam, and glycol-based fluids, including brake fluid.

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

Made of FDA-compliant EPDM, these O-rings are safe for direct contact with food. They hold up to a wide range of temperatures, and they won’t degrade from steam or water.
