Product Description

Product Description

Description

The WU7 profile is a non-symmetrical, hydraulic cylinder piston seal.The knife trimmed, beveled lip contacts the bore to provide enhanced low to high pressure sealing and wiping action. When installed, the diameter of the WU7 profile is stretched slightly to fit the gland. This ensures a tight static seal with the gland and improves stability in application. The WU7 profile is available in Parker proprietary urethane compounds providing excellent wear, extrusion and compression set resistance. The WU7 profile is a uni-directional seal. Two seals can be placed on a piston, back to back, in separate glands offering bi- directional fluid sealing.
