PARKER® STANDARD MOLYTHANE NON-SYMMETRICAL PISTON U-CUP

The UP profile is a non-symmetrical, hydraulic piston seal. The knife trimmed, beveled lip faces the bore to provide enhanced low to high pressure sealing and wiping action. The UP profile is a uni-directional seal. Two UP seals can be used, back to back, in separate grooves to provide bi-directional pressure sealing. The UP profile is an economical choice, available in Parker's® wear resistant and extrusion resistant Molythane® compound.
