Never having done this before, I need to replace the copper gas lines from the connections under the coach to the water and furnace appliances. The existing lines were in the way of the new frame re-enforcement I am installing. When I removed the covering I found both lines to be badly kinked in several places. Either someone previously had moved these around or that is the way they were when installed originally.

Looks like either 5/16 or 3/8 inch tubing.

What kind of copper tubing is used for gas distribution?

Will be another challenging job but want to do this before the re-enforcement is in place.

Thanks in advance for any info.

I replaced lines to the reefer and furnace, and got 3/8" soft copper at Home Depot. All connections are with flare fittings.

I was just at my favorite tube shop and they recommended Parker SS25UL rubber LP hose.


any comments?

I agree with your shop; running copper is tedious. I replaced and rerouted the reefer and furnace lines because they were buried in a trench at the back of the compartment - I don't like hidden gas lines.

Note that access to the furnace fitting and passing the line through the bulkhead may require removal of the door. The black D-shaped line passthrough slides out with the door removed.

Thanks Rusty

Got all the measurements and going for the hoses now. Will be so much easier than working with copper but will be pricey.

will have a bit of clearance problems below the furnace but I think there is a 45 degree connector that will take care of that problem.

I've noticed that many contractors are using a flexible yellow plastic tubing for gas connections now. Have you considered that?

When I converted our bus, I used all rubber lines. Handles vibration better. Disadvantage is that it can age.

Whenever possible, when running a copper line, I use a small radius tube bender to make a full circle to make any flexing evenly distributed. This lessens the chances of vibration or motion-induced failure.

I went with the rubber lines and it was very easy. Thanks for the comments.
I was amazed how deep the kinks were in the copper lines I removed.
