I've always used copper tubing and brass flare connections for propane plumbing at the camp.
The price of copper is making me reconsider and I am going to do some remodeling in the spring.
I see that PEX has pretty much replaced copper for water piping in most new construction around here, but I'm pretty certain that you cant use normal pex for propane.
Does anyone know of an economical alternative to copper tubing?

First off I am a ticketed plumber/gas fitter and owner of a mechanical contracting company, and to answer your question "NO", there is no plastic pipe that can be used for GAS only copper, black iron or sleved aluminum flex pipe.

Thanks for the replies. I'm assumiing that the sleeved aluminum flex pipe isnt DIY-able?
I think i'lll stick to copper, because i hate flaring copper a bit less than I hate threading pipe.

I've only done a little bit of gas piping, but the pieces I needed were readily available at Lowes...pre-threaded. Just measured first, then bought the lengths of pipe (and elbows, etc...) that I needed.
I would think with a little pre-planning it would work out OK.
I am thinking about all this stuff for my future cabin and security is guiding most of my decisions. Copper theft is pretty popular out here.

I ran quite a bit of iron piping in a home in the city that used gas lights and I made additional ones on remodel. I had never done it, but I found a old pipe vise and purchased the couple of sized thread cutters I needed. I found once you did a couple its very simple to thread the ends. The other thing about iron pipe is that you don't have to worry as much about something damaging it by accident. In the new home my mom recently had built the plumber used iron pipe but ran a couple copper lines off it for two propane wall lamps we had installed for emergency use. As explosive as propane is I think that a well built iron system is a bit more reassuring to me.

I just bought the 25 foot roll of the 3/8" copper pipe for gas. I double flared the ends and hooked them up. I just used it for my stove/oven, so it pokes through the floor behind the cabinets. Its all under my crawlspace, not in the walls, so no fear of driving a nail through it.
The cost of the rolled stuff is cheap compared to the more rigid stuff.
