OK, I'll assume you've never taken one apart, commercial kegs have an anti tamper device that prevents the removal of the spear, this vid shows you how to remove the spear and then grind off the tab so that next time you need to remove it, it's a simple matter of just unscrewing it.Have checked out sites on U tube but can’t find much information on how to disassemble an A Type keg spear to replace seals
thanks MarkThis might help. There is a better picture in the attachment.
There are only two serviceable parts in the keg. The CO2 Valve and a gasket between the spear and the keg body.
If the CO2 valve is at issue you will find it easily enough by pressurising the keg and putting some soapy water on the top of the valve.
The Gasket requires removal of the spear which isn't all that hard if you think ahead and get the right tools together first. No doubt there are lots of YouTube vids out there. This one isn't too bad How to open "A" type stainless steel keg for homebrew!! One tip, remove the gasket before you cut the safety tag off, a grinder or the sparks from it can stuff the rubber gasket pretty quickly. Funny enough I to have a pair of pliers with a bit of grinding done to them just for pressing down the CO2 Gasket and grabbing the spear.
I find the gasket is rarely a problem unless you are removing the spear regularly, if you are get some spare Gaskets opening and closing kegs will use them up a lot faster.
I just spoke to Linkon at Keg Services, he has them in stock and is willing to supply home brewers. Looks like you would be paying about $1 each plus postage, probably a minimum of 10 to make it worth their time. Must say the guys at Keg Services are doing some great work and are very good to deal with.

That's the same Tube as I linked to (slower than Grumblez).
Good morning Darren, it looks like you have most of it covered in terms of leak detection. You haven't talked about the regulator in your system. It may be worth trying a borrowed reg and see if that resolves the problem.
I have posted on this forum my frustration with leaking gas and in my situation using a commercial keg with an A coupler. Have gone through 3 x 6 kg gas bottles in very quick time. I have used all the soapy water tricks with nothing to show. I even bought another A coupler to try and solve the problem. Went back to basics and retighten all the connections, even though the soapy spray bottles yielded no clues. I am thinking there might be a problem with the actual spear in the commercial keg. Not sure how to tell or fix it.
appreciate your frustration
hey me ol mate. When you say "ball locks", do you mean the ones that are often used on commercial kegsHi Klosey, have you replaced the seals in the keg? No seal lasts forever.
I used these things for years back in my Landlord days and never had a problem, it's one of the reasons I've switched from ball locks.
HeyHo, long story short, Landlord back in the day, started to homebrew with bottles, commercial stuff just not available, came to Oz in 85, and discovered "hb kegs" paid $350 EACH for second hand coke cornies, commercial stuff in 20L just not available, 2004 went to PNG for 10yrs (that's a whole different story) came back and BOOM! the whole Chinese thing had taken off, got back into it and after 5/6 yrs of pissin around with Chinese HB gear (leaks, poor QC etc) suddenly remembered my old days of just hooking up a keg, and having it work. If nothing else the Chinese have provided competition in what was a closed market with ridiculous prices, so now you can get a commercial 20L keg made in Germany for about 20% more than a Chinese one, and 80% less than what it would have cost 20yrs ago (if you could buy just 4 or 5) It's the only reason I didn't look into it earlier.hey me ol mate.
