Description Details

Astoria Espresso Machine Part 26x20.5x2 Copper Seal (12158) is a precision-engineered component designed to ensure optimal performance and longevity of your Astoria espresso machine. Crafted from high-quality copper, this seal measures 26mm in outer diameter, 20.5mm inner diameter, and 2mm in thickness, providing a perfect fit and reliable sealing function. Copper’s excellent thermal and electrical conductivity, combined with its natural malleability, makes it an ideal material for seals subjected to high temperature and pressure conditions typical in commercial espresso machines.

This copper seal plays a critical role in maintaining a tight and secure connection between key machine parts, preventing leaks and ensuring consistent pressure control during the espresso extraction process. By effectively containing steam and water flow within the designated system channels, it helps maintain the machine’s efficiency and prevents damage caused by unwanted moisture exposure. This ultimately translates into improved espresso quality, minimal downtime, and fewer costly repairs, making it an indispensable replacement part for your Astoria espresso machine maintenance routine.

Ideal for professional baristas and coffee shops relying on Astoria equipment, the 26x20.5x2 copper seal offers durability and reliability even under heavy daily use. Whether you’re performing routine maintenance or an urgent repair, this component restores your machine’s integrity and helps maintain consistent shot quality. Available exclusively at Kaldi.com, the Astoria Copper Seal (12158) ensures your espresso machine continues to operate smoothly, delivering rich, authentic espresso with every pull.
