Double-Lip Snap-In Straight-Lip Hydraulic Wiper
Double-lip or redundant wiper lips are the most effective ways to improve a system’s sealing performance. Design provides interference fit with the housing for a better static seal on the OD. Straight wiping lip for aggressive dirt exclusion without scratching the rod. Integrated U-ring with a beveled seal lip facing the opposite side collects any leakage from the rod seal, providing for the driest rod sealing available. To prevent a pressure trap, it is important to use one of our long-life rod sealss that allow pressure relief; otherwise, a pressure-relief port must be present between the rod seal and wiper.
