Hi BB

I am totally non practical and have been wondering what I could find to stop the gas and yes that is obviously proven technology and would be delighted to press it back into service

Thanks very much ....will DM you soon

You could try shaving off a sliver of the rubber tube in case it’s a little too long, it takes almost nothing to go from long-enough to too-long.

If that doesn’t solve your problem then you may have a mythical beast that I’ve never seen. I have heard, but never seen, that this joint can leak. If this is your problem I don’t think you can do anything to fix it - maybe lots of heat and a good squeeze in a vice to press them together?

I’ve dropped an email to Hambleton Bard asking for their view.

I took a few of these apart in the past and the ones I had the non-return valve stem was threaded into the main body and I think they were thread locked as I had to heat them to unscrew them. Could be the thread lock wasn't done properly and is leaking :confused.:

If the gas is escaping through the pin, if you leave the empty bulb in place it should stop it as it has nowhere to go.

I had this problem with one of the new tops I bought for my old Boots barrels.
If I didn't unscrew the bulb it would hold pressure as I remember.

Pin valves seem to be of variable quality and their poor design/construction is usually the weak link in keeping pressure in barrels.

I since have gone back to the old tops, without a valve just pressure release valve, and keep it simple with dextrose to carbonate.
Works ok for me, so long as I don't drink it too quickly it will repressurise on its own .

Thanks all for replies - will trim new rubber and try on different barrel

They are, I’ve taken quite a few apart for various reasons. He might have a rogue that’s leaking up the thread. Incidentally I’ve never had the need to retain the inlet rubber tube with a small tie wrap, as you recommend. I would have thought someone would have to very heavy handed with an S30 cylinder to blow them off, or does it happen with Sparklet all-or-nothing applications? Replacement rubbers are best sourced from the silicon tubing used as fuel tubing for model aircraft glowplug engines, by the way.

The seal on the 8g bulbs can be thick or thin and brands are different so you can get used to one brand and the same twisting action can result in a more vigorous discharge. I’ve blown the tube into my beer myself in the early days.

Model aircraft and home brewing are probably not good bedfellows but I’ve done both (Still have a loft full of 30 year-old aero engines, radios, and boxes of “stuff” 😂 ).
