ES4 jam ring with gasket, carbon steel, zinc-nickel

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