Knock Box Parts

Replacement Knock Bars, Rubber Inserts, Tubes & Complete Knock Boxes — Home & Commercial — Australia

The knock bar is one of the highest-wear components in any espresso setup — used dozens of times daily in a busy café or home kitchen, it absorbs constant impact from the portafilter and gradually compresses, cracks, or loses its grip over time. When the rubber bar starts to degrade, knocking becomes harder, noisier, or less effective — and the puck stops releasing cleanly. Replacing it is a quick, inexpensive fix that restores your knock box to full function in minutes.

Di Pacci stocks knock box replacement parts — rubber knock bars, stainless steel inserts, replacement tubes, and complete knock boxes from Precision and Rhino — for home baristas and café use. All ship Australia-wide with fast dispatch.
