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.

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.

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

Replace the standard O-ring/backup ring combination with a more reliable alternative—these head seals resist twisting and remain stable even in applications with fluctuating pressure.

These rod wipers are also known as U-type wipers.

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.

These seals are commonly used in well, sump, and displacement pumps.

An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.

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

Rods along the barrel of these cylinders secure the end caps and shield the barrel from impact.

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

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

Replace failing or lost O-rings and gaskets in Norgren modular compressed air filters.

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.
