Upgrade your Gaggia espresso machine with this comprehensive tune up kit. It includes an IMS precision shower screen that provides superior water distribution for optimal extraction, a durable brass shower holder, a silicone gasket for a tight seal, and stainless steel screws for secure installation. The backflush disk helps keep your machine clean and functioning at its best. The 58mm x 14.5mm (2.28 x 0.57 inches) stainless steel shower holder with its wide 4 holes design fits all Gaggia Classic, Pro, New Baby, Evolution, Gaggia Coffee, Deluxe, Carezza, Coffee 97, Coffee Deluxe, Gaggia Paros, Tebe, and Saeco Aroma models. The IMS precision screen (55mm or 2.17 inches) with its 200 micron integrated membrane filter ensures much better distribution than the original equipment manufacturer (OEM) plate, resulting in a richer, more flavorful espresso shot.
