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.
Strengths
•Allow small radial cross sections Reduce the risk of contaminant adherence on the wiper lip Available in metric sizes If not in stock, alternatives can be produced by SKF SEAL JET systems
