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 | 75 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

The MPSU300 is a compact, double-acting piston seal consisting of two parts: a urethane sealing ring with a pronounced sealing edge and a rectangular nitrile energizer to prevent the seal from twisting within the groove. It also has low friction and smooth operating movement even at low linear velocities.

94A; 70/80A Durometer | Urethane Material | 74.5 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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 | 7 1/4 in Nominal Inner Diameter | 3/8 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 | 122 MM Nominal Inner Diameter | Piston Seal

Features

• Easy assembly
• Low friction capabilities

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 | 60 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 | 1.483 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.
