personaly i would braze it, better safe then sorry


(Interesting. I remember seeing a post on here that said that a typical solder joint would be rated to about 3000 PSI, including safety factor.)
very true^

i have personally tested regular water supply soldered joints up to 800 psi, no leaks with a hydrostatic pressure test( hook it up and pump water in at high levels of pressure)

and no blow outs

so regular solder will hold well on 1/2" copper pipe at 150 psi? I'm getting a mixed input here.

Yes, assuming you solder it properly.

if 150 psi is all your going to, you will be fine

OK, thats great! thanks for the help everyone!

make sure you clean the fittings very well and use flux, im assuming you already know that but just putting it out there
