MCW375-7000-312-H9BPolyurethane press-in wiper seal with a single lip and a steel retaining ring
Hydraulic wiper seals prevent contaminants from entering a cylinder assembly and hydraulic system. MCW seals are polyurethane press-in wiper seals with a steel retaining ring. They have an effective, single wiping lip that sits flush with the cylinder head. This design allows compact arrangements when the cylinder is retracted.
