Best way to attach EVABarrier to stainless tubing

[fuzzybee]

I'm working on my upright keezer build, and I'm at the point where I want to put my CO2 and beer gas tanks outside the freezer. I'll be using EVABarrier for my gas line (at least inside). I planned on getting BobbyM to bend some 1/4" OD stainless at 90 degrees to get the gas into the freezer. What would be the best way to attach the EVABarrier (4mm ID) to the stainless tubing?

Bobby could weld the ends on you need, if not you'll be dealing with compression fitting, which "can" leak.

Why not just use EVABarrier all the way to your regulator?

I want to back the freezer as close to the wall as I can, and I'm worried about messing up the tubing when I do that.

Maybe use an elbow?

fwiw, I used 1/4" MFL stainless steel bulkheads to get gas into and out of my fridges. When I switched to EVABarrier in the fall of 2020 I used the same 1/4" FFL to 5/16" OD tubing fittings on both sides of the bulkheads, and in the back added 5/16" OD 90° stem adapters to avoid kinking the tubing against the wall...
