Annealed copper conical washers with straight collar (also known as self-centring gaskets) serve as seals in fittings used in refrigeration and other applications.
Made of copper and annealed after blanking to increase ductility, they guarantee a reliable hermetic seal and a secure, long-lasting closure.
Technical Information
Copper Cu 99,9% as per EN 1652
