PTFE liquid......yes or no?

[HoppyTommy]

Just in the process of upgrading my kegorator. Currently have one beer tap and a single gas feed. Just upgraded to 3 beer taps and a 4 gas feeds via a 4 way gas manifold. I have space for four kegs in my fridge.

I tried to get the gas splitter in my fridge initially but realised it was too cramped, all the hoses were being bent and the whole lot seemed to leak. (Even with jubilee clips very tight on the barbs). I've since read on here the gas lines need to be very straight off the barbs and not too bent to ensure a good connection.

Consequently I've moved my gas board out of the fridge now. The gas lines are under far less tension.
I've managed to acquire some Oetiker clips and some PTFE liquid (advised by a patient of mine who works with gas lines). Has anyone used either of these? Any top tips for gas connections? Using grey gas line and 1/4 barbs (I think).

Many thanks

I wouldn’t bother with it, better to make sure all connections are clean and tight.

I use 3/8 line and JG splitters. And I have a JG tap on each keg. I also had trouble getting the manifold into my fridge and didn't want to drill lots of holes in my fridge so I settled for this.
You can get right angle JG fittings which might help but so far managed to get away without.

I use PTFE liquid on chemical lines at work and it doe,s work a treat but the fact that you are using in conjunction with CO2 which is then use to pressurize your beer is not so good.You could try using
Yellow double density, often labeled as “gas tape” as it will work better on your lines...

The stuff I've got is marked safe for hot and cold water pipes so I assumed it would ok for the gas lines. Would you not say this is the case? The way I've seen it used is on the barbs so in theory there shouldn't be any in contact with the co2.

You shouldnt have needed it on the barbs as they are designed to be self sealing against the pipe as they are a slight bit oversized to the internal OD of the pipe.
It is in contact with the CO2 as you would find if you don't use it to seal you will have a leak as it's intended to prevent this.
Check to see if it's foodsafe and if so certainly use it ..

You've got me sufficiently worried enough not to use it now. I'm going to try just the pipe, barbs and my fancy oetiker clips I think and go from there. Thanks for the guidance chaps.

All sorted. No leaks so far. Went for two turns of the gas tape on each barb and some Oetiker clips.
