The flowmeter O-ring creates a watertight seal within the flowmeter body, preventing water leakage around the rotor assembly and ensuring accurate volumetric dosing. A worn or damaged O-ring will cause water to bypass the flowmeter, resulting in leaks, inaccurate dose volumes, and potential water damage to surrounding components.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMaterial: Rubber\u003c\/li\u003e\n\u003cli\u003eRing thickness: 1.78mm\u003c\/li\u003e\n\u003cli\u003eInternal diameter: ø 28.30mm\u003c\/li\u003e\n\u003cli\u003eWeight: 100g\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat Is a Gicar Flowmeter and Why Does the O-Ring Matter?\u003c\/h3\u003e\u003cp\u003eGicar flowmeters are used in many commercial and semi-commercial espresso machines to measure and control the volume of water delivered to the group head for each shot. The flowmeter contains a small paddle-wheel rotor that spins as water passes through — the O-ring seals the rotor chamber to prevent leakage. Without a good seal, water bypasses the rotor, causing dosing inaccuracies and internal leaks.\u003c\/p\u003e\u003ch3\u003eWhen Should You Replace the Flowmeter O-Ring?\u003c\/h3\u003e\u003cp\u003eReplace this O-ring if your espresso machine is showing any of the following: water leaking from the flowmeter body, inconsistent or drifting volumetric doses, the machine delivering more or less water than programmed, or during any routine flowmeter service or disassembly.\u003c\/p\u003e\u003ch3\u003eHow to Replace the Gicar Flowmeter O-Ring\u003c\/h3\u003e\u003cp\u003eIsolate the machine from power and water and depressurise the system before starting. Remove the flowmeter from the hydraulic circuit, disassemble the flowmeter body, extract the old O-ring using a pick tool, clean the seating groove thoroughly, and fit the new O-ring ensuring it seats evenly without twisting. Reassemble and test for leaks before returning the machine to service.
