Don't replace with a non genuine seal because it want work as well. This product is perfect for the Ascaso Duo Professional. I had my machine serviced by a local machine servicer and they replaced with a non genuine seal and it didn't last 6 months and made it difficult to fit the group head. Now I have this part my machine is back to like new.

As described. Fits well. Coffee much improved. Spatter decoration of kitchen walls, bench and floor has been discontinued. Postage cost more that the part.

Good product. Works well.
