The Hallite 864 is a double lipped metal cased wiper, designed to press-fit into open groove housings. Hallite's 864 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 on 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. The Hallite 864 wiper is designed for use with venting U-rings such as teh Hallite 663 rod seal. Suitable for light, medium and heavy duty applications, the wiper has been designed to provide ease of installation and offers excellent durability in service.
