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.

Also known as Quattro Seals and X-rings, these X-profile O-rings have four points of contact for a better seal in dynamic applications than round-profile O-rings. They also require less compression to make a seal, so they offer a longer service life.

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

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.

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

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.

Harder than standard Viton® fluoroelastomer cord stock for better wear resistance.

The brown color of this cord stock makes it easy to identify.

More chemical resistant than standard Viton® fluoroelastomer, this cord stock is made of Grade ETP Viton® fluoroelastomer. It resists harsh chemicals, such as calcium hydroxide, methyl ethyl ketone (MEK), and nitric and phosphoric acids.

These 325-piece assortments mean you’ll always have a backup ring on hand.
