Question Pressure/Temp gauge stuck

My Pressure/Temp gauge doesn't work and needs to be replace, but it is hard to take out. Rather than taking a chance on breaking it off. I figure I can just leave it where it is and add a new gauge.
I was thinking to remove the 1" elbow where the hot supply riser and the supply manifold join. And replace it with a 1 x 1 x 1/2" Tee with a terminate on one end and add a female fitting to the top of the tee so I can thread in the gauge there. Is that a good location and is this a good idea?

That would be OK for pressure measurement. But, personally, I think the temperature function should measure the temp inside the boiler itself.

I have the exact same issue. How so I safely remove this thing?

Did you manage to take yours off?

9/16s wrench. They're tough to get out but they'll come out. The problem with a tee is that there is a shift behind the gage that needs room. It also needs to be inside of the boiler not in a pipe.

Too-Late advice

If you leave a gauge installed for a long time, particularly if pipe dope of Teflon tape wasn't applied to the threads, they can get stuck. Best to replace the gauge every 5-10 years, because they can go bad anyway. Alternatively, every few years, loosen the gauge a fraction of a turn and retighten.

dburr - 9/16 worked!
thanks for giving me the confidence to lean on it a bit.
I was scared that I would break something off if I pulled too hard.
