Accidental mixing of media can be avoided by equipping the hose and tank unit with a suitable selectivity. System slots (tank unit) and pins (hose unit) are positioned around the circumference of the couplings. The number of alternatives varies depending on the nominal size of the coupling.
TX couplings as of nominal width DN50 have seven selectivity positions. Please indicate all required positions in your order. You may select one or up to seven positions. This ensures high variance.
