Piston Seals

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

70A Durometer | NBR Material | 155 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

MPSQ piston seals are designed for bi-directional, low friction sealing with increased stability and superior leakage control. This seal is highly effective in applications requiring media separation or low gas permeation rate. This double acting seal is primarily used in accumulators and heavy duty cylinders.

40% Bronze Filled PTFE Material | 29 MM 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 1/4 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 | 7 in Nominal Inner Diameter | 1/2 in Cross Section | U-Seal

A double acting piston seal with many features: Two compact seal edges to concentrate the load against the dynamic surface, a cavity between the two external seal edges to retain fluid (reducing friction and wear), side grooves to allow pressure to load the energizer in all working conditions, high sealing performance at low pressure, excellent wear-resistance, and high resistance against extrusion.

97A; 70A Durometer | Urethane Material | 69 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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.

15% Glass Filled PTFE Material | 7.482 in Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

Manufactured from 55 Shore D polyester reinforced with <5% glass fiber, style PS1704 offers compact, low friction sealing for light to medium duty hydraulic cylinders. Style PS1704 is easily stretched over the piston without needing to be resized as in the PS1400 seals. Directly interchangeable with style PS1400 and PS1500 piston seals. Piston diameter “I” dimensions are given for pistons without wear rings.
