“Got the 1/4" Mater Pressurestat from Espresso Parts and am happy to repot that it worked perfectly in my Expobar Brewtus IV. I ran into difficulty getting the old one out but once that as done, installing the new one was a breeze. it doesn't LOOK identical to the original, but it FUNCTIONS exactly like the original and FIT just fine. No issues, no reconfiguring, no moving things around nor forcing anything to fit. It is perfect.”
“Replaced my old mater pstat as the boiler psv was lifting and the brew boiler was not heating.
The new one was a direct replacement and worked perfectly heating up the brew boiler when the steam pressure reached one bar. Old one lasted about 3 years”
