Fits the most commonly used Home Brew tank (a.k.a. Corney Keg) liquid (out) port.
Note: When using Homebrew fittings it is reccomended to use either an inline check valve or regulator shutoff(s) with a built in check valve. This is because Homebrew fittings do not have a built in check valve and check ball (standard in keg couplers). These features prevent the possibility of beer backflowing into the gas regulator and possibly causing damage.
