Description Details

Astoria Copper Gasket 8.5x5x1 (Part #12155) is a precision-engineered replacement component designed specifically for Astoria espresso machines. Crafted from high-quality, durable copper, this gasket ensures a superior seal within the machine’s group head assembly. Its exact dimensions—8.5 mm inner diameter, 5 mm thickness, and 1 mm width—make it a perfect fit, guaranteeing optimal pressure retention during the espresso extraction process. By providing a tight and consistent seal, this gasket helps maintain the machine’s brewing integrity, ensuring you enjoy rich and flavorful espresso shots every time.

One of the standout features of the copper gasket is its excellent thermal conductivity and resistance to wear. Copper’s natural ability to handle high temperatures without deforming or degrading under pressure makes this gasket highly reliable for long-term use. Unlike rubber or silicone alternatives, the copper gasket maintains its shape and sealing capabilities even after repeated heating cycles, reducing the risk of leaks and mechanical failures. This durability translates into lower maintenance costs and longer machine life, making it an essential part of regular espresso machine upkeep for commercial and home baristas alike.

Ideal for use in professional espresso environments, such as cafes, restaurants, and specialty coffee bars, the Astoria Copper Gasket 8.5x5x1 (12155) is a smart investment in maintaining peak machine performance. By replacing worn or damaged gaskets with this genuine copper component, users can ensure consistent pressure during brewing, which is critical for extracting the full flavor profile of espresso beans. Available exclusively through Kaldi.com, this part enables seamless machine maintenance and supports the delivery of high-quality espresso drinks that meet the highest standards of coffee craftsmanship.
