Piston diameter “I” dimensions are given for pistons without wear rings.
15% Glass Filled PTFE Material | 6.305 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
Piston diameter “I” dimensions are given for pistons without wear rings.
15% Glass Filled PTFE Material | 0.912 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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 | 4.408 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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.
55D Durometer | Glass/PTFE Filled Polyurethane Material | 7.754 in Nominal Inner Diameter | Piston Seal

55D Durometer | Glass/PTFE Filled Polyurethane Material | 0.941 in Nominal Inner Diameter | Piston Seal
Features
- Easy assembly
- Low friction capabilities
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 | 1 7/8 in Nominal Inner Diameter | Piston Seal
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 | 3/4 in Nominal Inner Diameter | Piston T-Seal

Buna-N Rubber Material | 5 1/2 in Nominal Inner Diameter | Piston T-Seal
Specifically designed as piston seals, these u-seals are engineered to seal on their outside diameter. They offer extended, service life and maximum reliability in piston sealing.
92A Durometer | Urethane Material | 4 1/4 in Nominal Inner Diameter | 3/8 in Cross Section | U-Seal
