Abstract

A coupling has a plastic socket part having a connection nipple fitted into an end of one of two tubes to be joined and having an outer surface engaging the lining of the one tube, a socket having an inner surface, and a conductive metallic lining layer on and extending between the inner and outer surface. A plastic plug part has a respective connection nipple fitted into an end of the other of the tubes and has an outer surface engaging the lining of the other tube, a plug having an outer surface and fittable in the socket, and a conductive metallic lining layer on and extending between the outer surfaces of the plug part. An electrically conductive seal ring is fixed in the socket and engages the outer surface of the plug part. The parts are made of polyoxymethylene and/or a fiber-reinforced polyamide.
