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.

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.

Fill irregularities in valve stem with these soft PTFE seals.

Also known as 100% GFO, these expanded PTFE seals contain graphite powder, which dissipates heat away from the shaft and allows pumps to run cool at high speeds.

These seals are made of PTFE fiber without a lubricant, so they’re harder than other chemical-resistant packing seals to handle high-pressure valve applications.

The most abrasion resistant of all our packing seals, these are made of PTFE-impregnated aramid fiber that has been saturated in a lubricant. They are for use in pumps.

Made of PTFE-impregnated synthetic fiber, these seals are for use in pumps.
