Hard Rubber Portafilter Insert (50 mm. Diameter) for Backwashing

Backflush insert is 50 mm. in diameter and made of strong, heat resistant, flexible rubber. Insert this insert into your portafilter basket, and use to backflush your grouphead (using Cafiza) if you don't have a blind filter.

Since the disk is 50 mm. in diameter, it can be used in any portafilter into which you can fit it, provided that it covers the holes. It should work with a 52 mm. portafilter, and could work up to the 58 mm. size. Please measure your portafilter.
