This sealing ring is purple and made from fluorine rubber (Viton®). This is BLÜCHER’s sealing ring for special applications. The material is particularly heat-resistant and resistant to oil, solvents and strong acids. However, the FPM seal has only limited resistance to e.g. butyl acetate, acetone and methyl alcohol.
