Title: Flexible gas lines
Post by: nigel_c on March 10, 2017, 02:33:00 PM
Kegerator will be getting a face lift soon enough and I'm looking to keep the gas cylinder outside the fridge so I can get 4 kegs on the go at a time.
What I'm looking for is the flexible gas lines you see in the YouTube vids from the states.
Has anyone gotten them or know where I can get them.
Something like this...... https://www.kegoutlet.com/dc910-gas-line-assembly-516-ball-lock-disconnect.html    is what I'm after. I'm sick of the hard plastic ones and I don't fancy trying to get 4 setup.
Cheers.

You need silicone tube. I use some I got with my old solar pump. Perfect size.

Unfortunately normal silicone tube that isn't braided doesn't have the burst pressure.

I've looked everywhere for that red co2 tubing, in the end I went for reinforced pvc.

You can get red reinforced pvc, http://www.flomax.ie/catalogue/sku.aspx?node_id=952eb8a1-9202-4a18-a5ff-edaa339a1dfb

I've the same job to do with my kegerator next week so I bought some gas line from keg kingdom (https://www.kegkingdom.co.uk/products/3-8-gas-tubing). Haven't set it up yet but it feels a bit softer than the opaque stuff.

Burst pressure hasn't been an issue for me. Been used for fast force carbonation at 45psi without issue. It's usually at 10-15psi on longer term.
The stuff I have is quite thick walled. I'd guess about 3mm wall.

I have some of the heavy gauge silicone tubing that I got in the US but really wouldn't recommend it for high pressures vs braided or proper gas line.

I rigged up a line today, i ramped up slowly and it got to 4 bar and blew close to one end so I guess if you don't want to go mad and it's thick it might work.

I believe the soft clear stuff (like with the Blickman beer gun) is a soft vinyl plastic unlike our clear pvc stuff in Woodies that gets hard when cold.

What does CH have to say?

Is Tygon tubing suitable CH?

Blichman beer gun material is PVC
So the whole thing comes down to plasticiser that makes the PVC flexible, only one has food medical approval.
I still wouldn't use it for beer but like Tygon Will if the wall thickness is good fine for gas.
Proper beer line is the only thing I would recommend here for beer, it's the most inert product I know commercially available in tubing.
Kinda surprised myself with my experiment earlier on the silicone and can see why it would be attractive.

Hows this working out for you ? did you get it from flomax in the end, can't see anywhere on the site that it is food grade.  I got some of ebay but its 5/6" and it is not a tight fit on the 1/4" barb, have it clamped to the last and had a leak last night and an empty keg this morning :( . Just wondering how this is working out for you before I order some.
