The Hallite 820 single-lipped, snap-in rod wiper is designed to fit North American D-style housings and has been developed specifically for use in harsher environments with heavy contamination, such as in agriculture, off-highway, and forestry equipment. These wipers include a dust lip to prevent contaminates from entering through the groove. They also have a ribbed inside diameter for low friction operation and to prevent pressure traps between the wiper and rod seal.
