Flexible even at temperatures as low as -80° F, these fluorosilicone O-rings will keep your fittings free from leaks. They’re often used on fuel and coolant hose because fluorosilicone resists many chemicals, including ethanol and ethylene glycol.

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.

PTFE gives these seals a slippery surface that allows rod speeds more than two times faster than our other piston seals.

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

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

The slippery PTFE surface of these seals allows rod motion up to seven times faster than our other rod seals.

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our buffering seals.

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

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

Made from glass-filled nylon for excellent wear resistance and strength.

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.

These seals fit in housing bores that meet DIN 24960.

Built for high-speed circulation and dispensing pumps, these seals have a short spring that facilitates speeds up to 10,000 rpm.
