3.500 X 2.884 X 0.246 TFB - PS2473-56 | CRC Distribution Inc.

Molded from a PTFE base material with 40% bronze and machined to exacting tolerances, this seal exhibits low friction and high strength corners are chamfered for cold flow resistance.

40% Bronze Filled PTFE Material | 2 7/8 in Nominal Inner Diameter | Piston Seal

Features

  • Easy assembly
  • Low friction capabilities

8.000 X 7.254 X 0.379 Piston Seal - PS2700-128 | 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.

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.

PS-PU-1.75x0.25 - PSU-1.75X1.37X.250 | 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.

PSQ-28, PA-BTFE-1.100X1.750X0.270 - PSQ-28 | 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.

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 | 4.77 in Nominal Inner Diameter | Capped Piston T-Seal

Features

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