The PSU Piston Seal, also known as a Uni-Ring, is a one-piece, double-acting laminated seal made from cast polyurethane. Its tough outer layer is infused with molybdenum disulfide to reduce friction and provide excellent abrasion resistance, while the softer inner layer functions as a static seal and energizes the outer diameter for full bore contact. The PSU is a versatile replacement for existing Uni-Rings and other seals with matching dimensions, including O-rings, O-rings with back-ups, T-seals, and U-seals.
