V72G is a fluoroelastomer (FKM) rubber, a Copolymer of vinylidene fluoride and hexafluoropropylene, coloured green for easy identification.

FKM materials typically provide excellent resistance to heat, aliphatic and aromatic hydrocarbons, chlorinated solvents and petroleum fluids. Fluoroelastomers offer superior O-ring sealing force retention over most other oil-heat resistant elastomers, with the exception of perfluoroelastomers.

V72G is accepted by the UK Ministry of Defence (MOD) to Defence Standard 02-337 part 1, issue 1 (NES 337) for use on naval ships and submarines.

Available in any sized O-ring (fully moulded up to 2.5m/8ft internal diameter) and custom designed components.
