The essential Copper Washer, 13.5 x 19 x 1.5 (Part # L100/1A, replaces L037/4) is a critical component for maintaining the pressurized integrity of your commercial espresso machine. Crafted from high-grade copper, this OEM-specified washer features precise dimensions of 13.5mm inner diameter, 19mm outer diameter, and a 1.5mm thickness, ensuring a perfect seal in high-temperature, high-pressure environments. If you are experiencing a "leaky connection on my espresso machine" or need to "stop steam leaking from boiler flange," this sealing washer is the definitive solution. Its annealed composition allows it to compress perfectly during installation, creating a reliable, long-lasting seal that prevents costly pressure loss and catastrophic equipment damage.
Using this genuine copper washer ensures you restore your machine's peak efficiency. The primary benefit of the L100/1A copper washer is its superior heat resistance and malleability, which eliminates common maintenance problems like "constant espresso machine drips" caused by old, hardened fiber or poor-quality metal washers. 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. Installation of the Copper Washer, 13.5 x 19 x 1.5 (L100/1A) is standard for many La Marzocco models, particularly those requiring high-pressure sealing. Preventative maintenance with high-quality components like this helps avoid unexpected downtime and the need for expensive "espresso machine leak repair services."
