EVA Barrier Line conversion

[Deadalus]

@RyPA I know you were leaning towards swaging it but here's the conversion on the 2 way manifold. Having to change out the ball valves prevents much if any cost savings. Brewhardware for instance sells a 2-way flared manifold for $24. The valves are $8.99 there. Looks like they also have decided to stock only flared manifolds, and have their own branded 3 and 4 ways with nicer ball valves. Also they standardized the incoming gas with that 1/4"mfl x 1/4" MPT adapter. I had all the adapters already plus one valve. This manifold came as part of a sweet deal I got last weekend. Swaging them on and using the oetiker clamps should be fine. You might get some beer into the QD at some point, it won't get past the check valve. Conceivably you might need to take the line off to clean it and resanitize.

I've been hanging out on this Lord of the Flies island too much. I must just swage the evabarrier onto the O2 regulator. It has a smaller threaded barb, not too sure about the threads. Didn't fit any of threads on my thread identifier. Possibly 1/8" NPT but for a one-off item I'm not sure I want to have to order twice if I'm wrong. It's one of those medical green O2 regulators.

I do have a swaging tool. I needed it for my copper CFC. It's really useful for irrigation trunk lines, which is not standardized.

Picked up my my package of 6.3mm ID EVA hose today at the PO. Just completed putting together a gas line for my single body Tapright regulator. I wanted to go with the valve and barb already on the regulator, and use the standard CMB ball lock connector.

Putting the connector on was no issue since 6.3mm is ¼” and I have 3/16” swivel barbs on hand. I just put the swivel barb on the connector (so I had something to hold onto) and pushed it right in. I clamped it with an 11.3mm oetiker clamp.
The barb on the gas valve attached to the regulator has a ⅜” barb. I slipped a 12.8mm oetiker clamp over the end of the hose, rubbed a tiny, tiny amount of keg lube onto the barb and went to the kitchen stove. I brought a small pot of water up to boiling and dunked an 1-½” of the hose in for 4-5 seconds. I inserted the tapered sharpening steel from our knife block into the end about an inch and let it all cool for a few more seconds. I pulled out the steel and the hose slipped onto the barb smoothly and snug. I tightened the clamp and was done. Really simple, and I am anxious to change out all my lines!

I'm just commenting about the standard lines being permeable.

As for connections, I had EVABarrier for a while with oetiker clamps holding them to barbs I'd stretched them over. Today I've got SS tubing in place.

Tell me a bit more about the SS please. Where did you get parts and how did you make connections?

McMaster-Carr, using compression fittings with NPT ends. The last foot or so at the kegs ended in a barb and some of the remaining EVA barrier line, so that it was flexible enough to not be a big pain to connect the kegs. Wasn't cheap.
