Message
V74C is a fluoroelastomer (FKM) material developed to offer extremely low compression set combined with excellent heat ageing properties. V74C has been engineered to retain its mechanical properties significantly longer than conventional FKM grades even under extreme temperature cycling, thereby providing increased service life and significantly lower the cost of ownership. V74C exhibits good resistance to acids and aqueous media, and excellent resistance to oil, fuels and hydraulic fluids at high temperature. Available in any sized O-ring (fully moulded up to 2m/6.5ft internal diameter) and custom designed components. Key Attributes Extremely low compression set and cumulative compression set providing extended seal life Excellent long-term high temperature stability Superior heat ageing properties for long-term sealing Typical Applications Vacuum pumps & compressors (high temperature applications) Mechanical seals Chemical pumps and valves Couplings and quick connectors
