Gas fitting alternative?

[pms67]

Hi
The John Guest (I think that’s what it’s called) fitting on my gas regulator keeps breaking, seems to get very brittle then just crumble and I’m getting fed up buying them, anyone got a better method of connecting?
Apologies if this is just obvious to most.

What exactly is the fitting doing? The grey threaded part that is.

That part screws into the regulator which fits onto tho Co2 tank

Any ideas why they keep going brittle? I’ve not had any fittings fail yet.

What regulator are you using so I can try and advise accordingly?

At a punt I would say it’s 3/8” to 1/4” MFL:

I would couple it with this push fit elbow:

I would go to a metal fitting as it may be the cold temperatures that are killing it. Does it need to swivel or be an elbow?
Quite a lot of the pneumatic fittings are metal for the threaded section then plastic for the push fit section, but you can get all metal too.
What size pipe are you using, and what size is the threaded section? Be careful with the pipe size as 6mm is standard to brewing but 1/4" is standard for water filters for some reason. One will fit the other (badly) but not the other way around.

I will check out the regulator when I get home, what a pita

It fits into this, guess it doesn’t have to be an elbow?

I think the grey pipe is 10mm? The elbow says 3/8
Does it need to be that type of pipe?
How do you guys connect from your regulator to pipe that feeds the quick disconnect gas post on your keg?
A couple of pictures would be soooo appreciated
Cheers

One of these should do - Just pick the right size. -

Just watch BSP sizes as they refer to the bore of the pipe not the actual thread size so you need a table.

Thanks mate
I think that would work fine, I will measure the grey pipe when i get home.
