DESCRIPTION
The MW-S metric wiper is designed to snap into a standard housing and provide reliable medium duty dirt exclusion. The proportions of the wiping lip ensure that it remains in contact with the rod surface to remove all deposits of mud and other forms of contamination except those found in heavy duty environments such as steel works and cement factories.
The inside diameter of the seal is provided with ribs to prevent the possibility of blow out due to pressure trapping of the main rod seal.
The MSWS is precision molded in polyurethane for maximum wear resistance and features a double-stepped should to fit tightly in the gland throat.
