External Pressure gauge

[teddysmith]

A quick question. Just trying to figure out the best way to fit an external pressure gauge to the flow just like below:

I'm going to be cold flushing the central heating but no boiler is attached just yet so I want to keep an eye on the pressure.

Many thanks.

The gauge will just be screwed into a branch from a tee I think.....so you can put the gauge at any convenient point.

Thanks. So I'm looking for say a Tee with a 1/4" bsp female fitting? or make up a fitting just not sure the exact fittings to fit!

Either a 22mm compression coupler female or elbow, then an appropriate sized bush 3/4" to 1/2" then a 1/2" to 1/4" unless you can find a 3/4" to 1/4" bush. Screw your pressure gauge into that.
