DESCRIPTION
The MW-H metric wiper is a double-acting wiper seal with both a wiper lip excluding contaminants from the hydraulic system and a beveled-lip, u-cup portion serving as a secondary safeguard against leakage past the primary rod seal. (H-wipers are not pressure seals). 
The shell is molded in polyurethane for light to medium duty hydraulic applications.
