Description Details
Ensure precise and reliable performance in your La Marzocco espresso machine with the genuine Belleville Spring 28X14,2X1.5 H2,15 (Part # I.5.004). This critical component, often used in group head assemblies or pressure regulation systems, maintains the calibrated compressive force necessary for proper component alignment and leak prevention. If you are experiencing inconsistent brew pressure or if your group head feels sluggish or sticky, it might be time to replace a fatigued spring. Our OEM Belleville spring is engineered for high heat and high-cycle stress, offering superior durability compared to generic alternatives, which is vital for commercial-volume operations. Investing in this factory-specified spring is the definitive solution to "fixing inconsistent espresso machine group pressure" or "replacing worn Belleville spring on La Marzocco."
The Belleville Spring (I.5.004) features specific dimensions: an outer diameter of 28mm, an inner diameter of 14.2mm, and a thickness of 1.5mm, all manufactured to H2,15 tolerances for perfect fitment. This exact calibration ensures the required spring load is maintained over thousands of cycles, guaranteeing consistent mechanical tension for vital functions like piston return or valve sealing. Key benefits include restored factory-level functionality, extended machine lifespan, and a reliable extraction process every time, solving the common "why is my espresso machine leaking after maintenance" problem by ensuring proper sealing force.
Installation of the Belleville Spring 28X14,2X1.5 H2,15 is an essential part of preventative maintenance for various La Marzocco models requiring this specific dimension. Replacing this small, yet crucial, wear-and-tear item eliminates mechanical creep and pressure variance caused by old, collapsed springs. Choose this OEM part to restore the consistency and precision of your professional espresso equipment and prevent costly downtime associated with "espresso machine internal pressure loss."
