quick couplings welding lines

Plugs and quick-release sockets on hoses for welding lines

Fitted to the pipes, these couplings enable the quick-release connection of hoses on the bottle and network and on the blow torch side. They can also to be used to make extensions. Stäubli geometrical locks remove any risk of swapping the circuits. The quick-release function means the lines can be connected and disconnected in just one movement and gas distribution stops automatically on disconnection.
