Espresso machine group head gaskets can last a while, but will wear and tear over time. The exact life expectancy of your gasket will depend on your usage, but you’ll know it’s time to replace it when you see steam or water leaking out of the group head while you pull a shot.

This replacement gasket is a premium silicone model designed for longevity, and it’s a little thicker than other gaskets of its size, meaning it seals tighter and lasts longer. This gasket is compatible with a number of 50-51mm group head machines. We’ve provided a fairly extensive compatibility list below.
