Performance Characteristics
- Chemical corrosion resistance including acid environments
- High temperature resistance for demanding applications
- Self-lubricating properties for smooth operation
- High wear resistance for extended service life
- Non-sticky, non-absorbing surface characteristics
- Excellent dimensional stability under varying conditions
Application Benefits
These back-up rings enable O-Rings to perform effectively in higher pressure applications where larger extrusion gaps exist. They provide reliable performance during reciprocating or rotating movements and maintain functionality across significant temperature fluctuations, making them ideal for hydraulic systems and industrial machinery.
