“I had to really work to put this gasket on the head of my machine using the butt end of a butter knife I had to press hard to work it on the the screen. This gasket was also recommended as a better replacement then the factory gasket and it is thicker then the normal one. I would probably recommend an 8MM version. As this was really tight when I put in my portafilter on twice I had the portafilter blow off the head of the machine.
I have an Expopar Office Lever”
