**Please note that we are not responsible for any damage before, during, or after installation. Damages can include over-tightening the gauge into the group head (causing the gauge thread to break and threading broken inside the group head) or breaking of gaskets and o-rings. **

This kit is compatible with almost all machines with E61 group including ECM, Quick Mill, Rocket, Expobar, Bezzera, Profitec.

***Half-turn with the paddle moving left to the right reduces the flow rate by around 3ml/sec***

The flow control device can be installed in machines that are equipped with standard E61 group heads. With just a couple of tools, your coffee machine will be able to vary the amount of flow using the stainless steel needle valve now installed on your E61 group. This needle valve is the main working component that allows the user to vary the flow of water to your coffee where you have full control of saturation and extraction of all that you love about your espresso!

Installation video will be provided.
