2.250 X 1.941 X 0.129 Piston Seal - PS2700-36 | CRC Distribution Inc.

This seal, molded from high grade 55D polyurethane, may retrofit the PS1800 seals, considering all dimensions are comparable. This seal material, with a high degree of memory, stretches over the piston and snaps in the groove for immediate assembly. These seals also feature low friction and high abrasion and extrusion resistance which helps to eliminate assembly damage. Piston diameter “I” dimensions are given for pistons without wear rings.

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.

PA-NEOFAB-3.25x4x1.187 - PSA-58-4000 | CRC Distribution Inc.

Style PSA-58 piston seals combine a heavy duty, fabric reinforced seal with two polyacetal “L” bearings. This construction allows the seal to withstand pressures up to 5,000 PSI. “L” bearings also react to pressure to prevent extrusion and support the piston. For 2-piece pistons.

PA-90URE-4.25x0.255 - PSC-344 | CRC Distribution Inc.

The Style PSC is a double acting piston seal designed to replace o-rings, quad-rings, and T-seals with the same groove dimensions (O-ring dash number). Style 575 urethane back-up rings may be added to either or both sides of the “PSC” to accommodate wider groove widths. The PSC is made of 95A Durometer polyurethane, giving it high extrusion and abrasion resistance. The crowned sealing surface produces a positive seal from vacuum to high pressure. Hercules® Sealing Products also offers a wide base (WB) Style PSC piston seal. These wide base seals have the same characteristics of the standard PSC seals but offer a wider base, eliminating the need to use back-up rings to accommodate wider grooves. Piston diameter “I” dimensions are given for piston without wear rings.

PS-PU-2x0.375 - PSU-2.00X1.50X.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.
