Re: Wood, Diesel or propane bulkhead heating stove?
Odds are that the copper fitting isn't brazed--probably a compression or flare fitting, in which case you don't have a continuous line. If you just run a new rubber hose from the solenoid to the heater you won't have to wonder if a fitting of unknown age or quality is leaking or if the copper has cracked anywhere. You may know that copper hardens where it flexes or vibrates and becomes succeptible to cracking. Rubber hose that's protected from chafe eliminates that worry. I think you'll find you need a seperate solenoid for each appliance, too. Otherwise all the lines get propane in them when you use just one appliance, defeating the purpose of the remote solenoid in the first place.
