Viton O-Rings and FKM O-Ring materials have excellent resistance to ageing, ozone, very low gas permeability (excellent for vacuum application) and the fact that it is self-extinguishing. Viton material is also resistant to oils, acids, and silicone fluids. Other key benefits include a temperature resistance range from -20°C to +205°C (or intermittent between -45°C and +230°C). This makes it ideal for applications within the Agricultural, Automotive, Aerospace and Defence, Petrochemical, Offshore Drilling, and Rail industries.
