How can we improve?

3,111 Products

Most Likely Products

O-Rings

Fit snugly into a groove between parts to create a leak-resistant seal

Piston Seals

Prevent leaks inside pistons by creating a seal against the cylinder bore

Backup Rings

Extend the life of O-rings and improve their performance under high pressure

Toilet Sealing Rings

Toilet Sealing Rings

Prevent leaks where toilets mount to the floor or wall

All Results

Sealing

Piston Seals

Prevent leaks inside pistons by creating a seal against the cylinder bore

Shaft Seals

Prevent leaks in motors, pumps, and gearboxes

Rod Wipers

Scrape dirt off rods to keep the inside of cylinders clean

Rod Seals

Maintain pressure inside cylinders and prevent fluid leaks

U-Cup Seals

With a lip on both the inside and outside edges, they can be used for sealing rods and pistons

Buffering Seals

Buffering Seals
