Designed to work with all Rocket Espresso machines. The Rocket E61 Bottomless Portafilter allows you to see directly whether the grind, the amount of ground coffee and the contact pressure were correct during the tamping process. Without the spouts, you save even more space and can place larger cups under the portafilter. Comes with a 21g triple shot basket. Note: This portafilter is intended for use with Rocket Espresso E61 group espresso machines. Some E61 group heads and factory portafilters have very slight height differences that are able to be overcome when using alternative portafilters by using a (thinner or thicker gasket) on the group head. Compatible with most E61 brew groups used by other manufacturers such as Appartamento, Profitec, Lelit, Quickmill, VBM, Flair 58, etc. This portafilter is NOT compatible with machines from the following brands: Bezzera (machines with a BZ style brew group) Breville Gaggia La Marzocco
