Characteristics and performance
The Hallite 831 single lipped, snap-in rod wiper is designed to fit metric housings and is interchangeable with many common European wiper styles. The proportions of the wiping lip ensure that contact is maintained with the surface of the rod to remove all deposits of mud and other forms of contamination except for those found in heavy-duty industrial applications.
The outside diameter of the seal incorporates a crush lip to provide interference fit with the housing and a face bead to ensure that the crush lip is not trapped in the corner of the housing. These features help prevent contaminant from entering the groove.
The moulded ribs on the internal diameter provide extra stability to the wiper and help prevent the possibility of blow-out due to pressure trapping between the wiper and the main rod seal.
