Description Details

Astoria Copper Ring Gasket 8X6X2 (Part Number: 12103) is a precision-engineered sealing component designed specifically for Astoria espresso machines. Crafted from high-quality copper, this gasket ensures an optimal seal between critical machine parts, preventing leaks and maintaining consistent pressure during the espresso extraction process. Its exact dimensions—8mm outer diameter, 6mm inner diameter, and 2mm thickness—make it a perfect fit for compatible ports and valves, guaranteeing reliable performance and durability under the high-temperature, high-pressure environment typical of commercial espresso machines.

This gasket’s robust construction also minimizes the need for frequent replacements, reducing maintenance costs and machine downtime.

Ideal for baristas, maintenance technicians, and espresso machine service professionals, the Astoria Copper Ring Gasket 8X6X2 (12103) is an essential replacement part to keep your Astoria espresso machine running smoothly. Whether you are conducting routine maintenance or addressing specific sealing problems, this gasket provides a dependable solution that helps preserve the machine’s performance and ensures every shot of espresso delivers optimal flavor and crema.
