Fit Cornelius ball-lock kegs. Also fits Firestone or Spartanberg Challenger V, VI, and Super Challenger ball-lock kegs. This releases at 30 PSI instead of the standard 90 PSI. The red color is handy as it tells you at a glance which kegs have 30 PSI relief valves on them.

Q: Is this for carbonating under pressure?
A: Yes, as long as you set the regulator below 30psi. Most people carbonate at about 25psi.
