Connect any homebrew keg fitting to any other
Homebrew kegging mixes push-in tube fittings, flare threads, tapered posts and BSP shanks that all look similar and mostly do not interchange. Pick the two ends you are trying to join and get the exact adapter, whether it seals on a flare, a washer or an O-ring, and the trap that catches people out.
