The device extends the threaded neck of the Smart Valve and retains the tank in the event of accidental tank/valve separation. The device also safely vents tank pressure without incidence of significant cylinder “take-off.” Smart Valve and 20oz. tank must be purchased as an assembled unit based on Smart Parts safety requirements.
Comes with an on / off valve, to make shutting off the CO2 flow to the gun easy - Just turn the valve off and unscrew the tank, saving you lots of air!
