I need to connect one end of Phyn Plus (1'' NPSM male thread) to a 1'' pipe (either MPT or FPT would work). Does such coupling exist? Water meter coupling is usually 1'' NPSM to 3/4'' NPT, I could use that with a 3/4'' to 1'' adapter, but I wonder if this can be done with a single coupling. Thanks!
Is there 1'' NPSM to 1'' NPT coupling?

Not an expert on this, but Mueller's catalog does list 5/8x3/4x1 as an available size for their H-10871N straight meter coupling, that would be 3/4" meter size (1" NPSM) coupling x 1" MIP. Don't know how hard it would be to source.
I also wonder if a 1" corrugated stainless water heater connector would work. I would think the nuts and washers would mate as well with 1" NPSM as they do with 1" NPTM, but I haven't actually verified that.
