PA-NEOFAB-3.5x4.5x1.25 - PSA-4500 | CRC Distribution Inc.

Designed to fit on one or two piece pistons, this piston seal employs a nitrile seal for high sealability, nylon split backups for extrusion resistance, and two split bearing rings. No further support bearings are required.

90A Durometer | Nitrile Material | 3 1/2 in Nominal Inner Diameter | Piston Seal

Features

  • Easy assembly
  • Low friction capabilities

PA-90URE-1.375x0.15 - PSC-216 | 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.

PA-98URE/NBR-2.875x3.250x0.250 - PSM-336-DPAC | CRC Distribution Inc.

This style of seal provides effective static and dynamic sealing while the groove on the sealing surface acts as a lubrication reservoir to reduce friction. Grooves on both sides prevent blow by during sudden pressure changes and a premium NBR square energizer prevents twisting. This product is molded from premium urethane which provides excellent extrusion and wear resistance.

PA-90URE-3.75x0.265 - PSM-340 | 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.
