DESCRIPTION
Our KBI-U wiper is a double lipped metal cased wiper designed to press-fit into open groove housings. This wiper comprises a specially textured polyurethane wiping lip which is securely bonded to a nitrided metal case, eliminating the potential for rust. Opposite the wiping lip are two sealing lips accurately produced and proportioned to collect the fluid passing through the rod seal.
Capable of operating in dirty conditions, the proportions of the polyurethane wiping lip allow it to follow the side movement of the rod to clear away heavily deposited dirt.
This wiper is typically found in Asian manufactured heavy equipment cylinders.
