Thanks for the idea, but that gadget won't be any help.



People don't understand what you're trying to do. There is no need to be a dick about it.



You just say "transfer." TO WHAT? A 1lb tank? Another 20lb tank? A larger stationary tank?



RV dealers sell high-pressure hoses with the tank connections, but without regulators for about $20 each, so all you'd need is a brass coupling from Home Depot to connect two of them together.



It's still not going to work: As soon as you tip the source tank over the OPD closes off the valve. You won't be able to transfer the liquid by gravity, and you won't be able to achieve a cold enough temperature on the destination tank using means available to you to "suck" the gas in and turn it back to liquid.



The only way to transfer is with a pump. You'd be $$$ ahead just venting the leftover propane to atmosphere so you can go to the refiller with an empty tank.

You don't need to vent it. The refiller will fill a partial tank. He'll still probably charge you for a full tank. Take it to a real propane store that sells it by the gallon in which case you pay for what you need.
