About O-Rings

Chemical-Resistant Ultra-High
Temperature Kalrez Rubber Sheets

Even when temperatures rise to 445° F, these Kalrez sheets are resistant to virtually all classes of chemicals.

Ultra-Chemical-Resistant Kalrez O-Rings

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.

Ultra-Chemical-Resistant Kalrez 4079 O-Rings
for Tube Fittings with Straight-Thread Connection

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.

Ultra-Chemical- and Steam-Resistant
Kalrez 6375 O-Rings

Kalrez 6375 O-rings are preferred over Kalrez 4079 for chemical-processing environments and applications involving steam.
