So, I've bought a new preset reg to screw into my 1.1 4500psi bottle. I've screwed it in all the way. When I go to fill it, the seal pops out , the bottle whips around and tries to decaptitate all the unamused onlookers and the guy from H-Pac looks at me with pity....
I tried thread locking in but the same thing happens.

what am I doing wrong?

I want to be able to remove the reg to fly to the States with it.

The seal pops out? which seal, and where's the air leaking from? and what make of reg is it?

this is what I have, on a 1.1 litre 4500 psi tank. The seal I'm talking about is the little black rubber ring you can see just behind the gauge. It's herniated out between the bottom edge of the reg and the bottle neck and pisses out from there

There should be no way the neck o-ring should be able to 'herniate' (good word!) through between the bottle and Reg, they should be flush. (you shouldnt be able to put a folded piece of paper down there) Is that the o-ring that came with the Reg or is it a replacement?

It's the original. it was the first time I had used it. :(

That sounds very bad! Check the threads (on both the bottle and the reg) for damage.

When you say you screwed it in all the way have you used a tool or just done it by hand?

The o-ring will prob need replacing now anyway but, try putting it together, look and see if there's a gap between the bottle and Reg?

Do not fill this with air

I did it by hand and used blue Loctite. This worked fine on my prevoius system. The o-ring is definitely knackered. Where can I get a replacement??

I can't actcaully get it apart at the mo...

If you can get it to me, Ill sort it for you.

but there may be a small 'beer tax' ;-)

I have hundreds of these o-rings in my workshop at Campaign. stop by one weekend and i will have a look at it for you.

Just so you know the o-ring's a symptom not the cause

The threads should extend enough to allow the o-ring to compress in order to make a friction grip and seal under pressure - as Jamie says if the o-ring is 'herniating' (great description btw) there is something seriously wrong - either damage is allowing it to be under very high pressure without the compression of the fit (if that makes sense) or a disparity between the threads is causing it to not compress enough and to form a seal - whatever it is be very carefull with this!

Kebab, if I bring this down to next Campaign walk-on, can you have a butchers at it?

we're all doomed, doomed I tell you!

Butchers....Very Apt!
