The plumbing can be had at a home store, it is a US size as are all
the fittings on any camper products sold in the US, I'm told.

I have used a harbor freight flare tool with excellent success. It
comes with a set of mandrels that go in the tube and keep it from
collapsing and makes the end flare to a standard size and shape. It's
so easy I've never had to do one over as far as I can remember. You
can roll it out straight on a table and then use either the spring
type or the pliers type of bender to get any shape used on a westy. I
have also used it to assemble the rather complex installation of a
permanently mounted heater that branches off from the regulated side
of the fridge/stove plumbing and crosses over to the sliding door
side.

If you need any help with the operation, just go buy one and email me.
I will get mine out and walk you through it.

It's very easy.
