Pressure guage adaptor for barrel cap

[Brewmarc]

I have just been given a pressure guage 0-30 psi, It has a 1/4 BSP thread with a 1/2" tail. Does anybody know whare I can get an adaptor so I can fit it to a pressure barrel cap? Or maybe someone here has found a different way of fitting. Any ideas welcome :

I've fitted 3 of these directly to the pressure keg cap.

The gauges appear to read zero in the pic, but they actually show 1.5psi.

Thanks for this :thumb: is it just self tapped into a hole in the cap or is there a nut & seal on the back?

There is a smali "O" ring between the gauge and the cap + a nut underneath the cap.

Very old thread I know but it keeps it altogether.
@Rodcx500z - You can fit a gauge into the cap of the King Keg rather than drilling into sidewall. Just about to fit this gauge to this cap, there'll be plenty of room both sides, might even fit another valve, one without the centre pin.
