V75G is a fluoroelastomer (FKM) material developed to offer good compression set performance and good all-round chemical resistance in operating temperatures up to 200°C (392°F). This material is used extensively in vacuum applications due to its low gas permeability and diesel engines where its broad chemical resistance, at medium operating temperatures, provides excellent long- term service life. Available in any sized O-ring (fully moulded up to 2m/6.5ft internal diameter) and custom designed components. V75G meets ASTM D2000 line call-out M2HK707, A1-10, B38, EF31, EO78, F15, Z1, Z2 (Z1 = colour green & Z2 = comp-set 30% max.). Key Attributes Excellent long-term sealing performance Broad chemical resistance Coloured green for easy identification Typical Applications Vacuum equipment Mechanical seals Marine diesel engines: Cylinder liners, Injection systems, Low temp. exhaust valve seals, Cooling channels
