Piston Seals

Some PS2000 piston seals utilize a round instead of a square energizer. Also, piston diameter “I” dimensions are given for pistons without wear rings. Many sizes shown are completely interchangeable with style PS914 piston seals.

Glass Filled Nylon Material | 2.712 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Compact and easy to install, the Style PSA-65 piston seal is a simple and economical design for pressures up to 3,000 PSI. The assembly consists of a nitrile rubber seal and two polyacetal bearings to support the piston. For 1-piece pistons.

Features

• Easy assembly
• Low friction capabilities

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.

Buna-N Rubber Material | 4 5/8 in Nominal Inner Diameter | Piston T-Seal

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.
