Made in Germany by C.M. Becker. For the beer side (usually marked OUT) of a ball-lock equipped keg. This fitting has a 3/8" outer diameter stainless barb, and fits 5/16" interior diameter beer tubing. Great for installing on the beer side of our Q73 Plate Filter.
To ease the 5/16" gas hose installation over the 3/8" barb and ensure a gas tight fit, heat the hose in hot water for a minute before installation.
