on and off

what does an on and off valve on your tank do??? is it good to get one?? thanks mike

ummmmm on/off pretty simple concept really ya see it turns the gas like on and off and stuff and if you had a really long hose called a remote going to your tank you could in theory shut off your gas so there wasn't as much waste when disconnect the tank from the remote hose...how ever most remotes have on/off valves themselves

i know that but then can u leave the tank on if the gas is off?? will it save enogh air to go buy one and spend 25 dollars on it??
