For upgrades, replacements, and custom Monster Valve air-up solutions, this is the Monster Chuck with no other fittings or valves. The current Monster Chucks are nickel plated for a shiny finish and are open, letting air pass through, whether it is on a Monster Valve or not. This means you'll need some other way to control the air flow while you're moving from Monster Valve to Monster Valve.
The open Monster Chuck does not trap pressure like the older closed chucks making it much easier to seat on your Monster Valve. This Monster Chuck is compatible with all generations of Monster Valve.
