Filling loop & Pressure gauge - Fitting

[Jumpy]

I need to fit a filling loop and pressure gauge without an expansion vessel, as I already have one in the loft so I want to be able to monitor pressure/fill up without going up there every time.

So, the filling loop is straightforward to fit, but its the pressure gauge I need help with.

All the gauges I see online are 1/4" fitting - so i have to get this up to 22mm to fit onto the c/h return.

I dont seem to be able to find any fitting that would do this conversion??

Anyone help as I'm sure I'm missing something / being dense!!??

Thanks

you can do it with these fittings 22copper x 22copper x 1/2" female iron tee plus a 1/2"x1/4" brass bush most plumber merchants will stock these or toolstation

Easiest, and most readily available bits, 22*22*15 tee (compression or solder, whichever suits you) then 15mm cu*1/2fbsp and 1/2*1/4 brass bush.
Or as him above says
