Shim/spacer for group gasket. Recommended usage is as follows:*

Machines 3-5 years old = 1 shim

Machines 5-10 years old = 2 shims

 *Do not use more than 2 shims. If leaking persists after 2 shims and a new gasket, it is time to purchase a new grouphead or a new portafilter

Note: As of 2021, we recommend the following part that may replace the standard undercup seal and shim combo. See Part# 1486050 This new silicon gasket is made to fit worn group heads and provide a good fit.
