Frequently Asked Questions

A: These rubber backflush disks are available in two standard sizes — 50mm and 57mm — to fit a wide range of home and commercial espresso machine portafilters. Please measure your portafilter basket diameter before purchasing to ensure a proper fit.
Q: What material are these backflush disks made from, and is it food safe?
A: These disks are made from silicone rubber, a durable, heat-resistant, and food-safe material. Silicone rubber is commonly used in kitchen and coffee equipment accessories due to its ability to withstand repeated high-temperature and high-pressure cycles without degrading.

The solid disk blocks water flow, forcing water and cleaning solution back through the brew group head and solenoid valve — effectively flushing out built-up coffee oils and residue. Refer to your espresso machine's user manual for the recommended backflushing procedure and frequency.
