PortafilterProcrastinator I was interested to see the use of PTFE tape on the main thread. I wonder if this is a worthwhile step to take? Does @DavecUK have any thoughts?
I don’t know, doing it might make the thread feel “tighter”, perhaps give less space for coffee to get in there. The only thing is PTFE thread has to be wrapped the right way and there is no right way on an adjuster that is twisted both ways. I don’t think it will do any harm…just don’t use too much.
In truth, it’s super difficult for coffee to get in there and it’s most likely to happen when cleaning. It might be better to wipe the threads out, perhaps following up with a toothbrush gently around them in one direction and lift when you get to the starting point (like cleaning a record)…a quick wipe with a kitchen towel and then a “smear” of food safe lube..again, don’t use too much…less is more. or a PTFE enhanced food safe dry lube if you have one.
