1.375 X 1.116 X 0.083 TFG - PS1400-22 | CRC Distribution Inc.

The PS1400 seals offer low friction and high strength in a compact double-acting piston seal design. The PTFE seal ring, combined with a rubber energizer, assures positive contact with the dynamic surface. The PS1400 is designed to fit ANSI/B93.32-1973 groove standards. Piston diameter “I” dimensions are given for pistons without wear rings.

PA-90URE-4x0.37 - PSC-342-WB | 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.

6.500 X 5.665 X 0.375 Piston Seal - PSQ-104 | CRC Distribution Inc.

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.

40% Bronze Filled PTFE Material | 5.66 in Nominal Inner Diameter | Piston Seal

Features

  • Easy assembly
  • Low friction capabilities

$133.38
/EA

A heavy duty double-acting assembly, the capped piston T-seal exhibits excellent sealability, extrusion resistance, and wearability. T-seals with “BR” suffix utilize a Bronze Filled PTFE cap instead of the standard Glass Filled PTFE cap.

PTFE; Nylon; Rubber Material | 5.02 in Nominal Inner Diameter | Capped Piston T-Seal

Features

  • Glass-filled PTFE cap, nylon back-up, rubber energizer
