Black pvc handle with M12 thread
This is the larger size threading for almost all commercial portafilters.
Before you buy:
Measure your own portafilter thread in case you have a different size, as there are narrow M10 size as well.
Check that you can remove your existing handle, as some come glued** and are very hard to remove.
💡If the portafilter handle is glued:
It might be possible to remove the handle by immersing the portafilter into a bowl of boiling water - leave the handle sticking up so it is not damaged.
Leave it for 10 min.,
Wrap a towel around the portafilter and try loosening the handle.
