Question by: Tommy W on Dec 4, 2025, 6:08 PM

got a hose end that’s 3/8-19 BSPP and the port on my block is 3/8-18 NPT. is this the right straight adapter to tie those together?

For matching those exact thread callouts, it bridges a 3/8-19 male BSPP on one side to a 3/8-18 male NPT on the other, in a straight steel adapter.

Got a piece of equipment running BSPP fittings and need to tie it into a standard NPT line. This the right adapter for that?

For exactly that kind of crossover, yes. One end is 3/8-19 Male BSPP (British Parallel) and the other is 3/8-18 Male NPT, so it bridges those two thread standards in a straight configuration. Both threads are the same nominal size, just different standards, which makes this a clean solution when you're mixing equipment that came from different origins. Keep in mind there's no thread sealant included, so you'll want to apply your own before making up the connections.
