I haven't heard anyone use that line and not use the push-type connectors.

That's what I realized once the tubing showed up today. Since I have barbed disconnects then I can't use these push-type connectors anyway. Correct?

Just found this, so evidently is HAS been done...

I wish I knew about these fittings when I bought my Kegerator the other day, it was a real pain to fit those barb fittings into the 4mm ID tubing (the pointy-nose pliers are definitely the way to go). These push in fittings look like they would make the process much easier. Nice work
 
I believe Bobby_M said one can stretch the 5mm ID tubing over a 1/4" barb with some heat and a tool like this

(Damn that's a lot of white space!)

Anyway, that's my intention on the gas side of my keezer, which is pretty much all 1/4" barbs (manifolds and QDs).
I'll be using the 4mm ID for the beer side which is all 1/4" MFL. With 6 lines with flow meters there's a crapton of JG fittings involved....

Cheers!
 
The quote is from a commentor to that video who wishes he had bought the duotight fittings instead of all the trouble he had getting the 4mm line onto his barbs, which shows that is CAN be done.

Gotcha. He must have more patience than I do. I may as well try it since if I return this I have to pay shipping back and may as well keep it around. Thanks for the info and looking into this for me. Very much appreciated.
 
Just talked to the customer service at morebeer.com and that tubing 5mm is for liquid side. I guess it can be used for gas too? It was too small for the manifold for sure. I think I am going to stick to the stiff vinyl unless I'm incorrect on all this?

EVA 4mm or 5mm ID line can be used for gas or beer, user's choice. I've opted for 5mm for gas and 4mm for beer as the former can be stretched over 1/4" barbs (which my 6 yo keezer is full of on the gas side) while the latter allow quite short lengths for the beer side. I'll be using a mix of JG and Duotight fittings on the beer side to get from 1/4" MFL QDs through 3/8" BSP flow meters to 5/8" BSP shanks.

fwiw, I received both lines today and got all excited because the bend radius is like 2" or so. That's actually tighter than the Bevlex 200 PVC beer lines and the braided Tygon PVC gas lines I've been using forever, so re-plumbing my tower box looks like it's gonna be cake :)

Cheers!
 
Or upgrading to mfl QDs. It would be silly to upgrade your lines and not upgrade your QDs.

I totally agree! #$^&@ homebrewing :) Always something to upgrade to. I'm keeping my current tubing and just cleaning it up a bit.
Just don't buy them from Amazon. They're some generic origin and at high cost.

For example, you can get real CMB QDs at RiteBrew for quite a bit less:
Gas MFL: http://www.ritebrew.com/product-p/843382.htm
Liquid MFL: http://www.ritebrew.com/product-p/843386.htm
 
I've stretched EVA 4mm ID over a 5/16" barb. That's as big as I'd want to go. If you wanted to try that, warm the end with a heat gun, insert something tapered with a light coating of keg lube or similar on the tapered tool. Let it cool a second, the push the barb in. Clamp with an oetiker clamp.
 
So I got the line today and I am unsure if it is the right size. I got the 5mm and am only doing my gas lines.

My manifold is this: https://www.morebeer.com/products/brass-gas-manifold.html

Did I get the wrong size?
I fit it over a standard 1/4" barb with some hot (not boiling) water and a tapered nail set to stretch it. I was able to fit the 4mm tube over a 1/4" barb too, so I'm sure the 5mm will go over a 5/16 barb.
 
Yeah, I almost made that mistake recently, needed to replace a half-dozen barbed beer QDs and saw a "too good to be true" deal. Then remembered to look closer and no CMB in sight.

If it ain't CMB it ain't happening here, that's for sure...

Cheers!

[edit/ps] CMBs a little cheaper than ritebrew...

why’d you replace gas line too? Is there a worry about oxygenation from the gas line side too?

I did it for same reason as @Robert65 but have found added benefit that these just don't leak as much as my old PVC gas lines with barbed fittings and worm clamps. My CO2 on the kegerator is lasting much longer since the swap. I'm using the push fit to flare fittings from @Bobby_M and the EVA barrier tubing he sells and would suggest spending a bit more $$ and swap out everything that has a barb at the same time. Just say no to stretching this stuff over barbs. Just do the whole project right the first time. I believe much easier than messing with barbs and clamps and then hoping for good and durable seals on the gas side.
