Does not come with an O-Ring. When replacing this valve, you should always replace the O-Ring.

Just what I needed and fits my cylinder perfectly! I dock a star because the order did not come with a o-ring. I had Marx brother fire in LA install the part and fill the cylinder. They said my cylinder needed a $7 test at the same time and installed the new valve for free.

Something g broke in my kegerator CO2 tank and it would not hold CO2. I figured I’d try to replace this before buying a Whole new tank and valve. Easy to install and now my tank is as good as new.
