Typical regular size for a faucet aerator is 15/16" male threaded or
55/64" female threaded, while junior size is 13/16" male threaded or
3/4" female threaded.

I have a 13/16" junior male threaded aerator for my bathroom sink and
need to replace it with my standard male threaded aerator.

Would someone confirm that I need a 13/16" male threaded to 55/64"
female threaded adapter, or point me to the correct adapter for my
needs? I'm having more trouble than expected finding such an adapter.
Thanks.
