This Rubber Portafilter insert is great for backflushing espresso machines. This is an easy & quick way to do the backflushing. No need to switch back & forth between the hot filter basket & blind filter basket. The thick rubber nib enables easy placement & removal even while hot.

Universal Size. Fits well with most sizes of Portafilters like 57 & 58 mm. For smaller sizes, this can be easily trimmed (only if required) using a pair of scissors.

NOTE: For Smaller sizes of Portafilter: Trim only after checking for size & attempt to backflush-as trimming may not be required at all.
