Softer than standard Buna-N O-rings for a better seal in low-pressure applications.

With flat edges on all four sides, 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.

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

These hard O-rings offer better wear resistance than standard Viton® fluoroelastomer O-rings.

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.

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

Made and bagged in an ISO Class 7 and Fed. Spec. Class 10,000 clean room.

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

These fluorosilicone O-rings remain flexible at temperatures as low as -75° F. They resist ethanol, ethylene glycol, and isopropyl alcohol.

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.

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

These O-rings withstand higher temperatures than standard EPDM O-rings.
