Group Filter Portafilter Holder Gasket 73.5×57.5x8mm – Rancilio & Bezzera
This Group Filter Portafilter Holder Gasket is an aftermarket espresso machine group head gasket measuring 73.5 x 57.5 x 8mm. Designed for compatible commercial and domestic espresso machines, this gasket helps create a secure seal between the portafilter and group head during espresso extraction.
This 8mm portafilter gasket features an outside notch and is designed for a range of Rancilio espresso machines, including older versions of the Rancilio Silvia. It may also be suitable for select Bezzera and Promac espresso machine models.
A worn or compressed portafilter gasket can cause water to leak around the portafilter, make locking difficult, or prevent the group head from maintaining a proper brewing seal. Replacing the gasket with the correct dimensions can help restore proper portafilter fit and reliable espresso extraction.

Replacement Rancilio Portafilter Gasket
The portafilter holder gasket is an essential sealing component that sits between the group head and portafilter. Over time, exposure to heat, brewing pressure, coffee oils, and repeated portafilter insertion can cause the gasket to become compressed or hardened.
Common signs of a worn group head gasket include water leaking around the portafilter, difficulty locking the portafilter into position, a loose portafilter fit, or an inconsistent seal during brewing.
The 73.5×57.5x8mm Group Filter Portafilter Holder Gasket provides a practical replacement option for maintaining compatible Rancilio, Bezzera, and Promac espresso machines.
Important Compatibility Note
For Rancilio Silvia, this gasket is intended for older versions and is not intended for Silvia V4 or V5. Because gasket dimensions and group head configurations can vary between machine versions, always compare the dimensions, notch configuration, and existing gasket with 73.5 x 57.5 x 8mm before ordering.

Part number 36-301-030 is listed for this part, except the dashes were removed. Unfortunately, Rancilio likes to reference parts with and without dashes in the part number.
