This is a replacement valve chamber seal for the 9Barista espresso machine, compatible with both Mk.1 and Mk.2 models.
The valve chamber seal plays a vital role in maintaining a pressure-tight environment inside your 9Barista. Located within the valve assembly, this small but essential component helps prevent leaks and ensures consistent pressure and flow during espresso brewing.
Made from food-grade silicone rubber, the seal is highly resistant to heat, pressure, and wear. It is precision-molded to match factory specifications and delivers long-lasting performance under daily use.
If you notice changes in brew time or pressure stability, a worn or damaged valve chamber seal could be the cause. Replacing it is straightforward and can help restore optimal function.
