Excuse me “HEMP” are youttalking about cotton Quick wwick OR lamp wick thread for threaded piping?.
I would suggest either teflon paste or teflon tape.
If someone did use hemp with pipe joint compound like Hercules pro dope or rector seal # 5 the possibility of this stuff expanding is non existent as the water would never come into contact with the internal threads of the fittings.
Teflon tape is much easier to work with and thus would be the choice I would strongly suggest.
