SKF PA 50X65X7X10 Polyurethane press-in wiper seal with a single protruding lip and a steel retaining ring

Hydraulic wiper seals prevent contaminants from entering a cylinder assembly and hydraulic system. PA seals are polyurethane press-in wiper seals with a steel retaining ring. They have an effective, single wiping lip that protrudes from the cylinder head. This design allows small radial cross sections and reduces the risk of contaminant adherence on the wiper lip.
