Cutting ring ES4 with a gasket, carbon steel, zinc-nickel

Cutting ring with a shaped gasket in the groove on the ring's cone and an additional O-ring gasket for DIN 2353 fittings. This solution blocks leaks caused by loosening of the metallic seal, e.g. in the creep process. Available as: L (series light) and S (series heavy). Surface coated with zinc-nickel with a layer thickness of 6-10 µm, which offers very high corrosion resistance (up to 720 hours without corrosion in a salt spray chamber). Material: carbon steel, zinc-nickel (sealing made of Viton).
