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.

Also known as grease seals, these are designed to retain thick lubricant at low pressure. They have a light grip on the shaft that creates less friction than spring-loaded seals.

A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals.

These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F.

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

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

Also known as speedi sleeves, use these to repair and protect worn shafts for a smooth sealing surface without machining.

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.

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.

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals.

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

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.
