Ribbed Buna-N over steel creates a tight seal with the bore, even when mating with a rough surface or in a split housing.
These seals have a metal case that creates a tight seal when mating with smooth surfaces.
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.
Designed with an extended lip, these seals have the flexibility to accommodate shaft misalignment up to 0.125". They're also known as clipper seals.
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.
A slippery PTFE surface allows these seals to function at speeds at least 25% faster than other rotary shaft seals.
Made from Buna-N for excellent resistance to oil and grease.
These seals are fluoroelastomer, so they have excellent chemical resistance and withstand temperatures up to 390° F.
An extended spring on these seals accommodates variations in seal cavity length and pump misalignment.

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.
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.
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.
Rated for pressure up to 10,000 psi, these leather U-cups handle over 80 times more pressure than our Buna-N U-cups.
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.
These seals have a beveled lip that optimizes contact against the rod, while a secondary lip keeps the seal stable.
