DESCRIPTION
The H-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. Also available in Nitrile for pneumatic and light duty hydraulic applications.
The H-wiper is also available in Fluorocarbon for a wide range of chemical media and temperatures up to 400F
