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

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.

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.

Flexible even at temperatures as low as -80° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol.

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

Thinner than non-sagging sealants, these flow easily into cracks and have a smooth finish.
