Quick JG adapter fitting question - 1/4 BSP?

[conorm]

Hi.

I have this pressure gauge : https://www.amazon.co.uk/dp/B0C1Z5Y9XJ

And want to connect it up to my corny keg lines. I use 3/8" OD lines. Am I correct in thinking that this will do the job? https://www.amazon.co.uk/gp/product/B00CAGPNM2

Either that or a reducing female to male bush/nipple combo straight on to a ball lock disconnect, that I can't figure out either.... this is a new world for me.

1/4 FFL is not the same as 1/4 BSP. The gauge has a tapered male thread but will fit a this…

Don’t over tighten.

The FFL thread will fit a threaded quick connect

Thanks, I had my doubts about the different threads!

So what's the thread size on a quick connect, e.g. a ball lock disconnect on my corny?

If you check out the Malt Miller site…

They refer to the thread as 7/16 thread. The thread is also referred to as 1/4 FFL….

You can see a 1/4 FFL has a 7/16”- 20UNF thread, hence the reference to 7/16.

Careful. I think the conversation has slipped onto "FFL": The gauge still has a 1/4"BSPT thread. I think you are after one of these (they are surprisingly difficult to find, JG don't seem to do them, shop about a bit, consider a new gauge with 1/8" BSP thread) : https://www.advancedfluidsolutions....ting-imperial-nylon-tube-connector-4015-p.asp

Hi @peebee . See my post #2 for a plastic version

I've bought a 3/8 BSP to 1/4 push fit off ebay, closest I could find. Just now need a 1/4 to 3/8 bush which I can pick up at local plumbing merchant, and a length of 1/4 OD tube which I'm sure I have anyway.

Forget you got the wrong one. Get those @Buffers brewery linked. They're Vyair, not John Guest, but I wouldn't have JG if they were half the price (even at 1/2 price they'd still be more than anyone else's anyway and will probably break on assembling). You don't want adapters so you can use the wrong sized adapter!

@Buffers brewery: Sorry, missed that post of yours (I missed it 'cos I thought I hadn't ).

Think you might have got the wrong one . The gauge you've got has a 1/4 BSP thread so a 3/8 BSP won't fit. (Well it will but it won't stay put ). The link I sent you gives you the option of a 1/4 BSP that will fit your gauge and a 3/8 push fit to match your pipe. No adaptors necessary just some PTFE tape on the gauge thread.
