Also known as Type B seals, loaded-lip seals, and PolyPaks, these U-cups are wider than our other O-ring-loaded U-cup seals for better stability and fit in wider grooves. An O-ring secures them to the rod or piston, preventing leaks at low pressure and as the seal wears. Because U-cups have a sealing lip on both the inside and outside edges, they can be used for rod and piston sealing. Pistons require two seals—install one facing in each direction.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

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

A square O-ring prevents these piston seals from rocking in the groove. They have a slippery PTFE surface that allows rod speeds more than two times faster than our other piston seals.

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals. They have two high-strength backup rings that protect against extrusion.

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

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

PTFE gives these seals a slippery surface that facilitates rod speeds over seven times faster than our other buffering seals. Use them in tandem with rod seals to protect the cylinder from pressure spikes and shock.

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

A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals. Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. An O-ring secures the lips to prevent leaks, while sealing against the housing. Press-fit seals into the bore around the shaft.
