0.5-1.2 BAR 1/4" Male BSP fitting. Preset at 0.8 bar. Used primarily in the Professional model. The Europiccola did not use the heating element including the female fitting for the pressurestat supply tube to connect to until circa 1992.
It should be noted that these pressurestats were not designed for successive or frequent adjustments, and doing so will significantly shorten the life of the part, which in our experience is short enough already (unfortunately these are NOT very robust).
