Hydraulic wiper seals are the first line of defense in many hydraulic systems. Unfortunately, they are also a perpetual problem for most users of hydraulic machinery. Microscopic scratches and gouges on the surface of cylinder rods can significantly reduce the life of wiper seals and give contaminants an easy path into the system. Particles as small as 5 microns can act like sandpaper on these surfaces, causing a chain of wear that grows exponentially in these fine-tolerance systems.
