This two piece piston seal design comes made with a heat-stabilized, thermoplastic step-cut ring along with a profiled NBR energizer. This product offers extreme strength and resistance to extrusion, a very high resistance to abrasion, and ease of installation thanks to the step cut design and chamfered edges. The design also allows the seal to pass over ports without damage and offers greater resistance to surface roughness in comparison to any elastomer seals. The profiled energizer offers improved dynamic sealing ability, responding quickly to pressure changes and providing excellent sealing characteristics under a wide range of pressure conditions.

T-Seals combine a resilient sealing ring with a hard, split back-up ring on each side of the sealing element. The assembly installs in a standard o-ring groove. T-Seals are non-spiraling and extrusion resistant to 5,000 psi with improved tolerances. Intermediate and Wide Base T-Seals are designed to fit MIL-5514F o-ring glands only and interchange with 1 o-ring / 1 back-up ring and 1 o-ring / 2 back-up ring grooves, respectively.

PA-90URE-3.25x0.265 - PSM-336 | CRC Distribution Inc.

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.

PS-PU-2.5x0.375 - PSU-2.50X2.00X.375 | CRC Distribution Inc.

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.
