Broken Pressure Gauge

you don't need to worry about high pressure- your pressure shouldn't be over 20-30 psi, and those gauges are designed for pressures up to 125 or better...
Old steam pipes were put together with threads, and had 50 psi at 250-300 degrees!
if the previous owner glued the pvc elbow over the existing port, I would make sure to leave enough when you cut it to attach another piece- but cutting and fitting in the adapter is a good plan

Ok so if i cut and attach a fresh piece of pvc to this "arm". How do I get the 1/4" threaded opening for the gauge? Ive been to lowes and home depot and I cant see anything that takes a 1.5" pvc and converts it to a 1/4" threaded opening.

you may have to step down a couple times- adapt from 1.5 to 1 to 1/2 to 1/4...
