Professional EPDM Backflush Disc for Espresso Machine Cleaning
The EPDM Ø50 mm Backflush Disc is a practical alternative to a traditional blind filter basket when performing routine espresso machine backflushing. Installed directly inside the existing filter basket, it seals the water outlet and allows cleaning solution to circulate through the brewing group, helping remove coffee oils and internal residues.
When used together with Puly Caff, it supports effective cleaning of the group head, three-way solenoid valve and internal brewing circuit, helping maintain consistent espresso quality.
No Separate Blind Filter Basket Required
Unlike a conventional metal blind filter basket, this EPDM disc is simply inserted into the existing filter basket already installed in the portafilter.
This makes routine maintenance faster and more convenient while eliminating the need for a dedicated blind basket.
Professional EPDM Material
The disc is manufactured from high-quality EPDM rubber, a professional material widely used in commercial food equipment thanks to its excellent resistance to heat, alkaline cleaning agents and repeated compression.
Its elasticity provides reliable sealing throughout repeated backflush cycles while ensuring long service life.
Why Is Backflushing Important?
During espresso preparation, coffee oils and fine coffee particles gradually accumulate inside the brewing group and the three-way valve. Regular backflushing removes these deposits, helping preserve espresso flavour while maintaining reliable machine performance.
For best results, the procedure should be carried out using a professional espresso cleaning detergent such as Puly Caff.
