Camlock connectors - can they be used for gas?

[Lochlannach]

I'm going to order some fittings to convert a sankey keg connector into a purging/cleaning/filling adapter.

I was thinking a couple of ball valves and camlock fittings which would allow me to connect various hoses to either port.

One thing I can't find out for sure is if the camlock connectors will work with gas - I will want to fill the keg with gas after cleaning/prior to filling.

Anyone know?

If not I could use a T and make separate inputs but that would need an extra valve etc. and make the adapter a bit unwieldy.

I'd say they'd be OK for the low pressure you'd need to purge the keg.

I was kind of thinking of using them to set initial carbonation levels too if they were up to the job - once the keg is filled swap to the gas hose and set the level.

From what I can find they're rated plenty high on the pressure front and from using the bigger ones in the oil business I reckon they'd be grand but I can't find a definitive answer or an example of them being used for gas.

What sort of hoses are you Gas could blow your hoses of you crank it up.
Why not John Guest fittings?

I've used them at work when stuck a good few times, they hold pressure fine.  They're not the safest though, because you can't vent the line before opening it and opening a pressurised connnection isn't much fun, which is why the Quickfit/Snapfit connections generally get used becuase they keep the line isolated.  You can use ball valves to isolate the line though and it will work fine, be kind of heavy though.

The idea is remove the NRV from the keg connector and put a ball valve on each. If I then fit a camlock onto each it allows me to connect a hose to the gas port to drain and another to the beer port to run in cleaning solution, sanitiser and I could swap the hose to fill with co2. I could then also use another hose to run the beer in from my fermenter via the same connector.

Good point though on the pressure in the line and venting. Probably have to have a ball valve on the gas line anyway for that reason.

[Lochlannach]

Maybe a T on the beer port with a camlock for the liquid and an isolating quick fit for the gas would be the way to go.

JG fittings are not meant to be used as quick disconnects (especially for gas). Yes of course they will work but eventually you will get leaks as the end of the tube gets rougher and rougher from the ss locking ring. Then all you do is cut off 1/2" of tubing. However unless you test for leaks every time you may end up loosing a tank of gas!

When used as QD beer lines you soon get to see the leak (and fix it)

Anyone know where to get a quick disconnect that seals for my gas line? All I can find seem to be open?

Late reply I know, but randomly came across this link yesterday and thought it may be useful to you

Snap-tite connectors are used a lot at work (pharma industry).  Never ordered off that site before, any time I had to buy them for work I got them off a local supplier in Cork (Hosetech, Liam A Barry), not sure if there'd be anyone local to yourself.
