Rigid and hard with a slippery surface, these PTFE O-rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and boric acid.

The FEP casing on these O-rings provides the same level of resistance to harsh chemicals as PTFE O-rings, but the core material is soft to make these O-rings more compressible.

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.

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.

These fluorosilicone O-rings remain flexible at temperatures as low as -80° F. They resist ethanol, ethylene glycol, and isopropyl alcohol.

If these O-rings deteriorate, they can be picked up by metal detection systems.

Also known as Boss O-rings, these O-rings are for use in tube fittings with a straight-thread connection.

This square-profile cord stock has flat edges on all four sides, which creates a better seal than round profile in static applications, such as hose, pipe, and faucet connections.

The X shape of this cord stock provides four points of contact for a better seal in dynamic applications than round profile. It also requires less compression to make a seal, so it offers a longer service life.

These PTFE backup rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and many acids.

These assortments include a mix of EPDM O-rings that resist water and steam and silicone O-rings that resist temperatures up to 450° F.

Rigid and hard with a slippery surface, these O-rings resist harsh chemicals, such as acetone, fluorinated solvents, methanol, and boric nitric, and sulfonic acids.
