CMB disconnects are made in Germany and are recommended by AEB, these are the best disconnects on the market.
Easily purchase a complete set up allowing the use of 3/8 beer and gas line with just one click. Always use the Black disconnect for Beer and the Grey disconnect for Gas.
Optionally, order 3/8 gas / beer line sold per meter. Beer and gas line is interchangeable.
These have a big advantage over barbed fittings in that the beer / gas line can swivel meaning less chance of a kinked line.
