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.

Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals.

These U-cup seals create less friction than O-ring-loaded U-cups, so they wear more slowly. Also known as lip seals, U-cups have a sealing lip on both the inside and outside edges, so they can be used for rod and piston sealing.

PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.

Avoid common O-ring failure in dynamic applications—the square base of these seals prevents twisting, while backup rings protect against extrusion.

These seals have a beveled lip that optimizes contact against the rod, while a secondary lip keeps the seal stable.

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

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our buffering seals.

A two-lip design means that these wipers also function as a rod seal.

These wipers seal against the cylinder housing to prevent contaminants from entering between the outside edge and the housing.

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

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.

Built for high-speed pump and valve applications, these super-tough seals are made of expanded-graphite yarn with carbon-yarn corners.

Our most compressible packing seals, these require less pressure than any other to make an effective seal. They’re made of lubricated PTFE-impregnated aramid fiber and are for use in pumps.

Synthetic yarn that’s comparable in strength to aramid is combined with graphite for soft seals that dissipate heat away from the shaft to extend the life of pumps.

Use these graphite-impregnated graphite seals for steam applications in pumps and valves.

PTFE has excellent chemical resistance and withstands a wide temperature range of -110° F to 500° F.
