Victoria arduino pump register knob aurelia ii nickel 07300818

What this control knob does

The Victoria Arduino pump register knob is the small nickel-finished control used to adjust the pump pressure register on Aurelia II espresso machines. It sits on the front panel and gives the barista direct, tactile control over pump output, letting fine adjustments be made quickly during service.

Signs it needs replacing

Over time the knob can loosen on its shaft, crack, or lose its grip surface from repeated turning and cleaning. A worn or wobbly knob makes precise pressure adjustment difficult and can eventually detach entirely, leaving the register shaft exposed and unusable.
