I've just bought a refurbished oxygen concentrator for running a very, very small oxy/fuel torch. Now I need to plumb it in...
It's a DeVilbiss 515, it comes with a plastic threaded connector to screw onto the concentrator; measuring the connector gives me 14.2mm OD and what looks like 22 tpi (possibly 1.75mm pitch). I wondered if it might be DISS, but the thread pitch seems wrong for O2.
Ideally I'd like to find an adapter that goes from that to 3/8BSP on the torch fittings (and I'm assuming this is not taper thread in this application?). Slightly less elegant would be to stick a hose barb on the 8mm ID PVC hose included, although I haven't yet spotted a parallel thread one.
Does anyone recognise this thread, please?
