10,731 products

Backup Rings

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

O-Ring Cord Stock

O-Ring Cord Stock

Cut to length to create customized seals

O-Ring Bonding Kits

O-Ring Bonding Kits

Everything needed to make O-rings

Shaft Seals

Prevent leaks in motors, pumps, and gearboxes

U-Cup Seals

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

Piston Seals

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

Rod Seals
