Hansen Beverage quick coupling socket with hose end. The couplings are available in two versions: for gases type 2HG and for liquids type 2HL. These versions are not interchangeable (different plug diameter), which prevents connection errors. Identifying the version is very easy. For gas couplings, the identification ring on the socket is white, and the hexagon on the plug has a notch. For liquid couplings, the identification ring on the socket is black, and the hexagon on the plug does not have a notch. Working pressure: 15 bar. Operating temperature: up to +130°C.
