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

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.

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 non-sagging sealants will not drip while hardening on vertical and overhead surfaces.

Much thicker than sealants for fine threads, these sealants bridge the gaps between coarse threads.

Remaining pliable over time, these high-temperature sealants protect against leaks caused by vibration and pressure—they naturally fill voids before leaks can develop.

This tape has a higher density than standard tape for a better seal between threads.

Made of PTFE, this tape has a slippery surface that keeps threads from binding to make parts easy to assemble.
