Molded from 93 Shore A polyurethane with a 70 Shore A energizer, this seal utilizes the same groove dimensions as a standard o-ring or T-seal. One or two Style 575 back-up rings may be used for wider grooves. Extrusion resistant by design, this seal is also resistant to rolling and twisting. Installation is an easy two step snap-in procedure with no need to re-size before insertion into the bore. Piston diameter “I” dimensions are given for pistons without wear rings.

These piston seals provide bi-directional, low friction sealing with increased stability and superior leakage control. The square cut energizer provides low pressure sealing and eliminates backside leakage. This seal also effectively seals between different fluids on each side of the piston seal, making gas/liquid sealing combinations possible. Piston diameter “I” dimensions are given for pistons without wear rings.

Our Style PSU piston seal, or uniring, is a laminated one piece double acting seal made of cast polyurethane. The tough outer layer is highly resistant to abrasion and is impregnated with molybdenum disulfide to reduce friction. The softer inner layer acts as a static seal and also energizes the OD to make full contact with the bore. This seal may be used to replace an existing Uniring or other seals of the same dimensions – O-rings, O-rings with back-ups, T-seals, U-seals, etc. Piston diameter “I” dimensions are given for pistons without wear rings.
