What can I solder Liquid propane gas line?
To the best of my knowledge propane gas line cannot be connected by soldering. You have to use compression fittings with a flaring tool like you would use to flare fittings on an automotive brake line, however if you are unfamiliar with gas and how to use it I would suggest using a reputable contractor who specializes in heating. I have installed lines in my own home, and also am a general contractor, but still get nervous when dealing with gas. It can be very dangerous and if no ventilation, may cause you to pass out or even possibly be fatal. Please be extremely careful, best wishes.
