Blow Tie. Blow Tie Blow Tie Blow Tie. Blow Tie.
Wasted lots of time, money, effort, and unsatisfactory beer with other DIY and prebuilt products. Ths spring poppet valves are unreliable and hard to adjust, they also leak considerably. Brass fittings get corroded by the moisture and gas. Tried the Blow Tie and was instantly thrilled, now have three. Can't recommend highly enough.
