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.

Swap out old seals without disassembling components—these seals come split for easy installation. They're also known as clipper 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 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.

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

These wipers seal against the cylinder housing to prevent contaminants from entering between the outside edge and the housing.
