This component is specifically used in sealing boiler elements, pressure gauge connections, and specific hydraulic joints where thermal cycling demands a robust, conformable gasket. Investing in this OEM replacement is the simplest and most effective way to address "why is my espresso machine losing pressure" and guarantee consistent, precise operation for your La Marzocco equipment.
For optimal performance and to guarantee longevity, always replace copper washers with new parts during any disassembly or repair involving high-pressure fittings.
