The F series fittings are designed for food industry due to the qualities of the material there are made from. The brass parts are chemically treated with phosphorus nickel-plating according to the NSF®/ANSI 51 standard of the food program. The seals are made of FDA-approved Viton (no danger of impurities coming from PTFE seal during assembly and disassembly). There is no technopolymer in the fitting, which excludes the problems of incompatibility with detergents and other chemicals. The fittings can be used in the temperature up to 150°C. Apart from food industry they are suitable for high-temperature applications in chemical, pharmaceutical, medical and electronic industry.
