Rocket Espresso Boiler Level & Safety Probe M199904821

Safeguard your commercial boiler with this genuine Rocket Espresso boiler level / safety probe, part M199904821. Threaded into the top of the service boiler, the OT57 low-lead brass body and food-grade stainless electrode provide a precise reference point for the autofill control board—topping up water when needed and shutting off power if the level drops too low. The insulated ceramic spacer withstands relentless steam heat, while the 6.3 mm spade terminal makes installation a quick, solder-free swap during routine maintenance. Replace tired or scaled probes and keep your heating elements, pump and customers perfectly protected.
