Backflush Disc – Blind Insert for Espresso Machine – Food-Grade Silicone – 3 Size Variations – Compatible with Cleaning Tablets and Powder – Wide Compatibilit (1, Black)

This product worked perfect for cleaning our Delonghi LaSpecialista Prestigio. I had the portafilter light on for a long time and couldn't fix it. This product along with a descaling tablet had me good to go in one try. Thanks!

This for perfectly in my 51mm portafilter! Nice and snug with the ability to reach and grab it. Unfortunately my cheap machine wouldn’t work properly to back flush. If you have a machine with an excess water discharge system, this product is PERFECT for backflushing.

I assumed it will completely block the filter. However there is a pour down, and my filter is 51mm.

Finding backflush disks for a 51mm espresso machine is impossible, This is a nice solution.

Worked.

Worked as it should with my breville cafe modena (single wall 51mm portafilter)

Does not work to offer a way to create a seal to preheat the Robot--the water just flows through it.

good fit for my 54mm portafilter, doesn't leak.

Prefer the stainless steel backflush.

Lovely

It is good hard silicone disk. But the size of this disk for my espresso machine handle is not perfect. I need 51. It sits nicely in single shot basket. But for double shot is too small and there is gap between basket and plug what makes backflush not so effective. I did use it and it did the job. But still think that is too expensive for "will do the job ok-ish"...
