Most weeping unions were never the right thread in the first place – BSP and NPT are close enough to start by hand and wrong enough to never seal (55° vs 60° flanks). If a fitting screws in easily then binds after two turns, stop: you are cross-threading standards. Gauge the thread, check the seat type – JIC seals on the 37° cone, BSPP on a washer, tapers on the thread – and seal each end by its own rules, not one rule for the whole fitting.
