Overview

This standard applies to detachable connections with outside threaded pipe G 3/4 A in accordance with EN ISO 228-1 used in the field of heating and cooling systems at the following hydraulic connection points: connection between radiators or circuit distributors and the respective pipe. Another connection point, for radiators with integrated valve sets, is the screw connection to the connection fitting or to the screw connection itself. This standard specifies the dimensions for the outside connection and the double connection. On the market, a series of geometries (outside threaded pipe G 3/4 A with inside cone and counter geometries), for example, under the designation "eurocone", are commonly used but are, however, only compatible with each other to a limited degree. Therefore, this standard is intended to achieve a unification of detachable connections with outside threaded pipe G 3/4 A and inside cone. Significant known applications are connection geometries of radiators with integrated valves, connection fittings and bypass connection fittings on radiators with integrated valves, ascension pipe valves for standard radiators, heating circuit distributors to underfloor heatings and radiator connection systems and the interface between radiator nipple and thermostatic valve or lockshield valve. Detachable connections with the outside threaded pipe G 3/4 A are normally made of metallic materials. Further variants are possible. So far, the designation "eurocone" has conveyed the impression that there is a standardised geometry. However, this is not the case, that is, the screw in or thread lengths, the cone angles and diameters, as well as the diameter of the inner cylinder differ frequently. Furthermore, the following variants are commonly used: spherical or tapered cone, cones with and without inserted sealing material, sealing principles inside the cylindrical part of the geometry comprising O rings, O rings within the slope of the cone (O rings offered by different providers are designed for different press fits) and sealings without additional sealing material (metallic sealing).
