This 8.5mm replacement gasket can be used in an espresso machine with an E61 brew head, which conveniently includes all Rocket Espresso machines.

The gasket around the brew head should be changed every year or so to ensure a good seal between the portafilter and the brew head during extraction. A major sign that the gasket needs to be replaced is if you notice water leaking over the top of the portafilter during extraction.

Please note: Replacing this gasket is part of the normal wear and tear/maintenance of the machine and is not covered by your warranty. Please only purchase this to install if you feel technically skilled enough to do so, as we cannot provide any technical assistance over the phone.
