Piston Seals

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.

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 | 2 3/4 in Nominal Inner Diameter | 1/4 in Cross Section | U-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 | 5 1/4 in Nominal Inner Diameter | 3/8 in Cross Section | U-Seal

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.

92A Durometer | Urethane Material | 1 3/4 in Nominal Inner Diameter | 3/16 in Cross Section | U-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 | 2 1/8 in Nominal Inner Diameter | 3/16 in Cross Section | U-Seal

This capped piston seal consists of a filled PTFE cap, a T-shaped NBR energizer, and two split nylon backup rings. It exhibits low friction, high sealability, and excellent resistance to extrusion and wear.

PTFE Material | 102 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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.
