PA 125X140X9X12Polyurethane 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.

Hydraulic wiper seals prevent contaminants from entering a cylinder assembly and hydraulic system. DTW seals are polyurethane snap-in wiper seals. They have a single-lip design, with two additional radial and axial static seal lips that maintain the sealing contact and keep the wiper tight in the housing. Notches on the inside edge prevent the seals from trapping in pressure or being pushed out by pressure.View product
