Hardware Store Vinyl tubing for gas line??

I need to get my 20lb Co2 tanks gas lines plumbed into my Sanyo 4912.

The local hardware store had clear vinyl tubing that said it could be used for gas and had a working pressure of 55psi. Any reason to not use it? My current lines are red PVC from Midwest but only ~4ft each.

FWIW: I'm planning on running the two lines up through the drain hole on the rear shelf, if I was able to drill the upper right back corner of the fridge I could probably use my current lines but I haven't seen anyone else do this yet...

as long as its downstream from all regulators you might be okay. make sure it woven reinforced as well

Regulator is on the tank so the line is downstream, but it wasn't woven, just regular clear vinyl line.

thick walled or thin like a siphon tube?
thick is fine i wouldn't use the thin stuff tho

It was fairly thick about the same ID & OD as the Red line I got from midwest...

You can also try your local welding supply shop. They may have the tubing. Mine has everything I need. Edit: Restaurant supply may also work well
