Anyone work with diving air bottles??

One of my full size diving air bottle valves has started to leak. I dismantled it and temporarily fixed it, but it needs replacing. Ideally I need the whole assembly that screws into the neck of the bottle. (I use the bottles in the workshop or to take on call out jobs, not for diving). Ebay shows ones in the USA, has anyone access to this sort of thing over here please? Thanks.

Like most things in life, the deeper you look the more you realise there's a lot more to learn. This "diving bottle" may not be a "diving bottle", but an industrial bottle, as the valve has a tapered thread where it enters the neck of the cylinder, with PTFE tape round it. Apparently this is not how "diving bottles" are made...They always use an O ring seal like the one in the Ebay photo.

 

The helpful guy on the phone at your Ebay link (cheers David...), says it sounds like a "25E" fitting, which as about a 1" OD taper thread.. The search continues!
