The Ball Lock Gas In Fitting fits the most commonly used home brew beer tanks (a.k.a. Cornelius or Corney Kegs) beer gas (IN) port.
NOTE: When using homebrew fittings it is recommended 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 back flowing into the gas regulator and possibly causing damage.
