A puck screen is essential for those who want to make better espresso. The puck screen helps to keep your brew head clean and extract smoother, more even, and more balanced, resulting in a higher fat content in espresso and a more mellow coffee taste. We have different sizes of pucks, such as 1mm and 1.7mm, to help you choose the right one for your coffee ground dose. Choose a thickness of 1.7mm when the coffee ground dose is normal, which does not affect the normal extraction. When the coffee ground dose is larger and very fine, it is recommended to choose a thickness of 1mm puck screen.This puck screen holder is easy to clean and soft. You can use your puck screen wherever you need it. The silky soft silicone material won't scratch your equipment, even if you use it daily. The espresso puck screen excels by effortlessly fitting into various 54mm portafilters, eliminating the need for tilting during installation. This ensures a flawless extraction experience for coffee enthusiasts who seek precision and compatibility with their machines.Specification:Product Name: Espresso puck screen.Size: Puck screen diameter: 53.5mm / 2.11inch.
