OHM Solid Piston Seal
OHM is a robust heavy duty double acting piston seal commonly used for the most demanding high-pressure application.
It comprises of a T-shaped elastomer (NBR) which provides the initial energizing for effective sealing at low and high pressures.

Description
Structural Design:
The elastomer pre-tensions the special type backup ring onto the pipe wall, while the thermoplastic bearing provides the nitrile rubber sealing element with resistance to compression.
The OHM seal integrates the benefits of compact design, low friction and high performance in a single piston seal.
Its design offers overall stability, wear resistance, seal ability,Low friction compact grooves, easy installation and maintenance free long life.
Summary of Advantages:
- High pressure capability
- Excellent pressure surge absorption capability
- Best combination for load holding and low friction sealing
- High resistance to abrasion
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
