Hallite® Type 846

The Hallite 846 double-lipped, snap-in rod wiper is developed specifically for cylinders applications on mechanical handling equipment, particularly those with long stroke, and designed for use with venting U-rings, such as the Hallite 663 or Hallite 673 rod seal. The design minimises the oil transfer out of the ram on the cylinder rod by collecting traces of fluid passing the rod seal.

Another special feature of the Hallite 846 wiper design is the thin membranes which vent when excessive fluid pressure is trapped between the wiper and the rod seal. This prevents pressure from ejecting the wiper out of its housing. After release of this pressure, the membranes close to protect against contamination from the outside without the need for an expensive vent hole in the gland.
