Restore perfect pre-infusion and flow rate consistency to your commercial espresso machine with the genuine Gicleur .8mm M4 Stainless Steel (S/S) (Part \# A.5.100, formerly L087/8). This critical flow restrictor is engineered to exacting specifications, featuring an ultra-precise 0.8mm internal diameter. This precise dimension ensures a standardized flow rate of approximately 500ml per 30 seconds (depending on pump pressure), which is vital for achieving consistent saturation and extraction across all your espresso shots. Made from durable M4 stainless steel, this gicleur resists scaling and corrosion, offering exceptional longevity in high-volume settings. If you are experiencing **inconsistent espresso shots due to uneven pre-infusion**, upgrading to this OEM-spec gicleur is the exact solution for maintaining quality and machine health.
The gicleur's primary benefit is eliminating variation in the brewing process. By precisely regulating the water volume and speed delivered to the group head, it mitigates the effects of fluctuating line pressure and ensures gentle, even puck saturation before full pump pressure is applied. This prevents channeling, leads to a sweeter cup profile, and significantly reduces the need for constant micro-adjustments. This component is essential for technicians performing **routine flow rate calibration on commercial espresso machines** and is a direct replacement, designed for perfect compatibility with various La Marzocco and other high-end models that utilize the M4 thread pattern. Its reliable performance solves the common problem of **espresso machine flowing too fast or slow**.
Installation of the Gicleur .8mm M4 S/S (A.5.100) is a quick process for qualified personnel, securing the critical link between your pump and group head. This small but mighty component guarantees the precision required for specialty coffee extraction. Its key features include M4 threading for secure fitting, 0.8mm restrictor size for optimal pre-infusion performance, and stainless steel construction for maximum durability. Don't let scale buildup ruin your coffee quality—if you are searching for **how to fix espresso machine pressure problems** or **replace a clogged gicleur**, the A.5.100 is the genuine OEM part that ensures your machine operates at its designed, reliable peak performance.
