The Hallite 864 is a double-lipped, metal-cased wiper is designed to press fit into open groove housings of popular Asian housing sizes for a wide range of applications and for use with venting U-rings, such as the Hallite 663 or Hallite 673 rod seal.
The polyurethane wiping element is bonded to a nitrided metal case eliminating the potential for rust. The polyurethane wiping element has a precision trimmed sealing lip to collect the fluid passing the rod seal and a specially wiping lip is textured to provide improved dry rod performance, particularly for long stroking cylinder applications.
The proportions of the polyurethane wiping lip follow the side movement of the rod to clear away heavily deposited dirt and make this wiper an excellent choice for dirty conditions.
The Hallite 864 is moulded in Hythane® 361, Hallite’s high-performance polyurethane, for excellent durability in service. The Hallite 846 is also offered in Hythane® 181 for lower friction and good low temperature flexibility.
