The object of the invention is a tapping armature (13) having an armature housing (18) made from plastic for liquid transport and storage containers, which are equipped with a plastic inner container (2) having a filling port and a drain port (12) for connection of the tapping armature (13), an outer casing made from metal mesh or sheet metal, and a pallet-like base made from metal. The tapping armature (13) with the filling port (20) of the armature housing (18) is screwed to a connecting flange (21) designed as a threaded flange and made from an electrically non-conductive plastic material, which is welded to the drain port (12) of the inner container (2) . The connecting flange (21) of the armature housing (18) is connected to the base of the outer casing of the transport and storage container via an earthing lead made from an electrically conductive plastic material. The connecting flange (21) and the earthing lead are produced in two production steps with an injection moulding machine according to 2K technology. In a further embodiment of the tapping armature, the connecting flange and the earthing cable are injection moulded as a single part from an electrically conductive plastic, and the earthing cable is connected to the flange ring of the connecting flange by a tear-off film. |
