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.

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.

FDA compliant for direct contact with food, these Buna-N O-rings create a strong seal in food and beverage lines.

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

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

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.

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.

These durable O-rings bounce back to shape after repeated compression better than other types of Viton® fluoroelastomer O-rings.

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.

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

Inherently softer and more compressible than PTFE O-rings, these Kalrez 4079 O-rings have comparable chemical resistance.

Made of Kalrez 6230, these O-rings are for use when high purity is essential, such as with food and semiconductors.

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

Able to withstand temperatures up to 400° F, these O-rings are softer than standard silicone O-rings for a better seal in low-pressure applications.

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.
