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.

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 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.

PTFE gives these seals a slippery surface that facilitates rod speeds over seven times faster than our other buffering seals. They're rated for pressure up to 5,000 psi.

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our 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 rod wipers are also known as U-type wipers.

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.

The flared end prevents this compressor from following the piston into the cylinder.

Also known as a wrinkle-band compressor, this tool has fewer points of contact than other compressors for less friction.

Reduce the risk of distorting and breaking piston rings during installation and removal.

Made of Gore PTFE, these premium seals are soft, so they conform to fill irregularities caused by wear in valve stems.

Aramid and PTFE fibers are blended for seals that resist chemicals and abrasion. Use these seals in pumps.

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

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.

Made of graphite-impregnated carbon, these steam-resistant seals dissipate heat from the shaft to protect pumps and valves when operating at high speeds.

The Inconel-wire reinforcement in these expanded-graphite yarn seals ensures they keep their shape longer than the High-Flexibility Steam-Resistant Packing Seals. Use them for steam applications in valves.

These seals require lighter packing pressure than standard oil- and water-resistant packing seals, so they cause less friction and reduce shaft wear. They’re made of graphite-impregnated aramid fiber and are for use in pumps and valves.

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.
