V80D is a fluoroelastomer (FKM) material developed to offer superior long-term low compression set and heat ageing properties whilst operating at high temperature.
V80D has been engineered to retain its mechanical properties longer than conventional FKM grades combined with excellent chemical resistance to petroleum, silicone, air and diester-based fluids.
Meets Aerospace Specifications DTD5612A & DTD5543B Grade 80.
Available in any sized O-ring (fully moulded up to 2.5m/8ft internal diameter) and custom designed components.
Key Attributes
- Excellent long-term sealing performance
- Superior heat ageing properties for extended service life
