I have a device that has 1" male NPSM (straight) threads on both ends and I want to adapt it to 1" NPT. The instructions say to get two water meter fittings to make the connection to NPT, but water meter fittings are typically asymmetric (1-1/4" NSPM to 1" NPT or 1" NPSM to 3/4" NPT).
I’m wondering would the female half of a union (like this one) work? Naively it seems like it would, but I don’t know if unions are always (or even typically) NPSM threaded, or if they’re just some random straight threads that aren’t standardized.
Thanks for your help!
