Espresso Puck Screen in 316L Stainless Steel (AISI 316L (1.4404)) is used for spreading shower-head water evenly over the espresso puck and keeping the group-head screen clean. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.

Where 316L Stainless Steel Espresso Puck Screen Is Used
- Barista accessory brands: puck screens sold with distribution and tamping tools.
- Home espresso enthusiasts: shots with less channeling and cleaner shower screens.
- Café workflows: faster group cleaning between shots during service.
- Machine OEMs: factory accessories for single-boiler and lever machines.
Ordering Espresso Puck Screen in 316L Stainless Steel
- Diameter: Choose 0.2–0.5 mm under the basket inner diameter so the screen sits flat without binding.
- Thickness: A 1.7 mm sintered screen raises headspace use; a 1.0 mm single-mesh screen suits shallow baskets.
- Construction: Sintered multi-layer screens are rigid and stay flat; laser-cut single mesh is lighter and cheaper.
Mistakes to Avoid with Espresso Puck Screen
- Leaving the dose unchanged so the screen touches the group gasket and the portafilter will not lock.
- Buying a screen sized to the basket rim rather than the inner floor diameter.
