Chimaera cooling pressure test

[l10tus]

I'm trying to source an adapter to fit the male thread on my 1994 blue capped expansion bottle neck.
I have a proprietary pump up pressure testing kit, but can't seem to find a suitable single adaptor for the VAG blue capped aluminium expansion vessel.

Anybody any ideas or can give me a link to buy one please?

Swirl pot plug is 1/2" BSP, make up an adaptor to fit in there or the Otter switch, M22 x 1.5

You can buy rubber bungs for turbo system pressure testing etc that may help providing you can get the connection to work for you.
