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

Pair these O-rings with metric sanitary fittings, which are commonly known as aseptic fittings. Made of PTFE, they’re rigid with a slippery surface and resist harsh chemicals such as acetone, fluorinated solvents, methanol, and boric acid.

Unlike silicone, the Viton® fluoroelastomer core will continue to ward of chemicals should the FEP casing wear away.

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

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals.

A square O-ring prevents these piston seals from rocking in the groove.

The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.

Made from MDS-filled PTFE for a slippery surface, these wipers allow rods to move three times faster than other rod wipers.

Made from PTFE, these wear rings have a slippery surface that allows rods to move at least three times faster than nylon wear rings.
