A complete, performance-focused and durable upgrade kit for E61 grouphead espresso machines. This kit combines four essential components that directly influence how your machine ex tracts espresso and maintains pressure over time. Each part is selected for durability, precision, and compatibility with daily use. E&B Lab Nanotech Shower Screen (200 µm membrane)Ensures more even water distribution across the coffee puck and reduces buildup thanks to its low-adhesion nanotech covered surface. The most durable option on the market. Made in Italy. Cafelat Silicone Group Gasket (8 mm)Provides a stable, flexible seal with longer lifespan compared to standard rubber gaskets. Improves portafilter fit and reduces leaks. Molykote 111 Silicone GreaseSupports proper gasket installation and operation. Prevents sticking, tearing, and premature wear. Made in USA. Paper Shim (Spacer)Allows fine adjustment of portafilter lock-in position if needed. These components work together as a system: the E&B LAB screen controls how water reaches the puck the gasket controls pressure and sealing the grease ensures smooth operation and durability the shim corrects mechanical fit when needed When combined, they restore the grouphead to stable, predictable performance.
