Description
Structural Design:
OUY is an asymmetric piston seal designed to offer effective bore sealing in a wide variety of applications.
The external dynamic lip is shorter and stronger, providing superior sealing and compression deformation characteristics compared to traditional U-shaped rings.
Summary of Advantages:
- Good dynamic and static sealing
- Relief grooves against dynamic pressure
- High extrusion resistance
- Thin oil film and very good locking feature
Typically made from polyurethane, alternative materials can be provided upon request to suit your specific needs.
