The Normcore Puck Screen is designed to prevent water channelling by delivering water more evenly to the coffee bed. Simply place it on top of your coffee puck before attaching the portafilter to your machine. Now available with a PVD coating, this upgraded version increases durability and enhances thermal stability for everyday use. The ultra-slim 0.2mm option offers an even thinner profile compared to the 1.7mm version, making it easier to fit inside the filter basket, especially when a full dose requires a slimmer screen.

Stainless steel - Made with high-grade stainless steel, the puck is durable and easy to clean. 150-micron holes - For optimal delivery, the puck features 150-micron filtration holes.
