Plugs and quick-release sockets on hoses for welding lines - RBO, RBA and RBP

Fitted to the pipes, these enable the quick-release connection of hoses on the bottle and network or blow torch side. These couplings are also 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.

Applications: quick connection of oxygen, acetylene and other fuel gas lines.
