About O-Rings

Chemical-Resistant Soft Viton®
Fluoroelastomer O-Rings

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

Low-Outgassing Chemical-Resistant
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.

Chemical-Resistant Super-Resilient
Viton® Fluoroelastomer O-Rings

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

Chemical-Resistant Brown
Viton® Fluoroelastomer O-Rings

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

Chemical-Resistant Brown Viton®
Fluoroelastomer O-Rings for Tube
Fittings with Straight-Thread Connection

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.

Ultra-Chemical-Resistant Kalrez 4079 O-Rings

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

Ultra-Chemical-Resistant
Super-Resilient Kalrez 7075 O-Rings

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.

Ultra-Chemical-Resistant
High-Purity Kalrez 6230 O-Rings

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

Made-to-Order Chemical-Resistant
Fluoroelastomer O-Rings

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

Water- and Steam-Resistant High-Temperature EPDM O-Rings

Water- and Steam-Resistant
High-Temperature EPDM O-Rings

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