Recognise this fitting?

[rcx132]

Does anyone recognise the brass fittings that you can see on the ends of the probes of this cavity gun? They look like mini versions of PCL-XF fittings. I want to make some more probes for my cavity gun and want to find more of these fittings. Pretty sure my air fed mask has the same fitting to connect it to the belt assembly.

rectus?

Googled what @123hotchef and @pdg said, both are right. PCL call these "mini couplings" and Rectus call them Rectus 21 and they are cross compatible. Just ordered a pair with tail ends, £2.50 each.

yeah they are rectus 21 fittings, tried it on my tig cooler this morning

I use them on my welders and gas bottles makes it easy to change between gases

They also look a bit like foster fittings.
