small quick connect for tig torch

[finyuk2005]

just wondered if anyone knew what i need to be searching for for the tiny quick connect for the tig torch on a Lorch welder?
I want to be able to use my old CK torch that has a 6mm id hose.

the connector on the lorch torch is roughly 5mm diameter (the thinner diameter, there is also the larger diameter ring to hold it in) and 10mm long, looks a bit like this;

but im just not sure if that is the exact size i need!

cheers for any help

I just bought a connector on AliExpress, with the required diameter (there are different diameters) for my gas hose. And installed the “mother” in a permanent place in the body of the welding machine.
This job is not difficult

Lots if measurements there check against the one you have

^ that one won't fit, the lorch gas connector is very tiny. Very nice quality, but tiny.

There was a thread on here with the answer in iirc, i could do with finding out myself as well actually.

The control socket is 5 pin Tuchel (buy genuine as cheap copies are rubbish)

The gas connector is rectus 20KA

The water connectors are rectus 21
