M&P makes custom and standard PEEK back-up rings.
- Custom sizes up to 24” outer diameter.
- Standard sizes from the Back-Up Ring Chart.
DESCRIPTION
PEEK™ back-up rings are designed to prevent extrusion in elastomer O-ring sealing systems.
Elastomer O-rings serve as effective seals for dynamic and static applications in hydraulic and pneumatic equipment systems. A drawback of elastomer O-rings is their tendency to extrude into the clearance of mating surfaces with increasing pressures and temperatures. Higher temperatures impose a severe burden on the physical and mechanical properties of elastomer O-rings, which further increases their tendency to extrude. The combination of high pressures and high temperatures is a common occurrence in fluid systems. This establishes the need for the back-up ring in preventing O-Ring extrusion.
M&P makes various types of PEEK™ back-up ring designs.
PEEK BACK-UP RINGS MATERIAL
Virgin PEEK™
- Engineered thermoplastic.
- PEEK™ can be used up to 480°F
- is FDA approved.
- Excellent chemical resistance.
- Very low moisture absorption.
- Good wear and abrasion resistance.
Glass filled PEEK™
- PEEK™ with the addition of glass fibers.
- Glass fibers reduce the expansion rate and increase the flexural modulus.
PEEK™ is a registered trademark of VICTREX.
