The Sirai (pronounced "SUH-RYE") commercial pressurestat for 110~120/220~240V equipment, #P302-6. This is the part that regulates your boiler heating via a diaphragm that expands and contracts as the boiler steam pressure raises and lowers, activating the contacts and sending a signal to the heating element telling it to turn on or off. It is by far the most common pressurestat used historically and today.

Of course in most cases any presurestat will work, but if there is room for it go with the Sirai. It is a purely mechanical part, and so there's no micro-switch to go out. The diaphrams go bad, and the contacts get fried. But the Sirai is essentially two or three pressurestats, depending on how many wires are used in your unit. There are six connections. When the contacts on the first set of contacts go bad, simply move the two wires over to the next available unused set.

European Espresso machine manufactures use British Standard Pipe fittings in their equipment. To measure a fitting, one measures the inside diameter of the male thread on a fitting. In most cases. Specialized fittings of course may have a wider or more narrow opening depending on the application and desired volume or flow rate through the fitting. But for the most part, it's the inside of a male fitting that is measured. A 1/4" Male BSP fitting will measure 13 mm (1/2") on the outside diameter, for what that's worth....
