I have been using the clear poly tubing from the hardware store with
my Meco, (using propane and oxy) for years....inexpensive, flexible,
and lightweight. After 5 years, still no problems.
You can use hose clamps to attach them, or if you have a hose
fabricator in the area, they can crimp attachments on to the ends of
them for you. It's a great way to go.
