Navojni priključki z zareznim obročem - spojke s prizemnim obročem iz jekla in nerjavnega jekla, DIN EN ISO 8434-1 (DIN 2353)
Cutting ring screw connections acc. to DIN EN ISO 8434-1 (previously DIN 2353), colloquially "Ermeto screw connections", are intended for universal use with hydraulic pipes made of steel or stainless steel, copper pipes or polyamide pipes. They are compatible with the cutting ring screw connections made of brass. During the assembly of PA pipe or thin-walled copper pipe, reinforcing rings must be used. With the use of copper pipe we recommend using cutting ring screw connections made of brass. These cutting ring screw connections are to use for hydraulic applications with high pressures. We recommend the NC compression ring fittings offered here for use in corrosive environments, or special requirements for leak tightness.
