Thanks guy's for the humour as well as the help.

Danny, I'm not the carpet cleaner, it's for a mate of mine. I have a business in IT.

Mac, we've tried here in Oz and cannot find anything with US thread. Add to that the images I'm seeing don't quite match up to what I'm expecting. Probably a difference in manufacturer's approach but it does make it difficult for me to identify things with sufficient confidence.

Your suggestion about brazing some fittings together is OK, except I don't have anything with the right threads to start with - I may have to turn something up on my lathe (provided the thread cutting gearbox will allow me to get the right pitch) but I'm not really looking forward to that little task. Much easier to just buy the right ones from the US - or at least I thought it would be.

For example, how does this guy clamp to the hose?

I can't see the hose side and it doesn't resemble similar things here in Oz enough for me to be confident that it's the unit I want. An added difficulty is that the quick connect side is a different design to the ones we use here so I need to get ALL the connectors.

OTOH, this one is fine: http://www.factorydirecthose.com/site/932652/product/QC10M
And this one would be OK if I was sure of the thread:

You're only paranoid if you're wrong!
