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 Type B seals, these U-cups are wider than our other O-ring-loaded U-cup seals for better stability and fit in wider grooves.

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

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

For use in air-powered cylinders, these seals prevent the piston from slamming against the cylinder body to minimize wear and noise.

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

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.

Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.

Also known as oil seals, use these to retain oil on rotating shafts in motors, pumps, bearings, and gearboxes. A spring secures the lip against the shaft, preventing messy leaks. Press-fit seals into the bore around the shaft.

Built for small circulation and dispensing pumps, these seals have short springs.

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length.

Replace failing or lost O-rings in ASCO Numatics modular compressed air filters.

Replace failing or lost O-rings in Wilkerson modular compressed air filters.

Also known as pancake cylinders, these deliver as much force as other cylinders, but with a shorter stroke to function in small spaces.

Made to fit the most common mounting footprint, these cylinders have an NFPA (National Fluid Power Association) industry-standard footprint, ensuring easy interchangeability.

Cylinders have two parallel piston rods that prevent twisting as they extend and retract.

Replace all the seals on the rod end of a hydraulic cylinder.

Create an airtight seal around items. This sealer heat seals the bag and removes air at the same time.
