The primary role of a wiper seal is to provide a physical barrier to limit the ingress of moisture, dirt and other contaminants from piston rods used in hydraulic systems into the primary sealing system. This prevents external contamination from damaging internal seals and other system components.
Wiper seals are typically used in conjunction with other sealing elements and require a snap in fit into rod groove locations, complimenting a primary sealing solution.
PPE manufactures wiper seals in a range of sizes and high performance elastomer materials.
