I've got a weber BBQ and was thinking of buying the Companion Framed Single Burner would this adaptor be suitable to run both appliance?

Would this fitting screw onto a typical 9 kg gas bottle and allow us to connect to BOTH a typical high pressure gas stove, AND a regulated 3-way refrigerator? We'd like to have the fridge run all the time, and the stove, only when in use (and preferably be able to turn off the supply at the bottle when not in use).

I want to use my circa 1980 Companion stove along with a new 100 cm Gasmate pole connected to a lantern. I'm sick of the hassle of getting LPG refills and would prefer to pick up the pre-filled Gas'n'go cannisters from the petrol station. Could I screw this double 3/8" BSP adapter onto another adapter (for a POL cylinder). If yes, which shape adaptor would work? The straight one?

Can this be used to connect my 3 burner camp BBQ to the caravan gas bottle after the regulator. The line from the regulator is a copper line.The BBQ uses a higher pressure hose will it work off low pressure. Am I better off running an adaptor straight from the gas bottle.

Hi, we're trying to find something that will connect both our Gasmate Voyager and portable stove to the one gas bottle without needing to change them over for each use. Would this adapter achieve this? Our stove has the same connector as the Voyager. Many thanks
