what thread is in the gauge block, noticed the used one I ordered has an oring in the bottom
-
Well it's NOT NPT (tapered pipe thread) if it seals with an O-ring.... Likely 1/8-27 NPS or 3/8"-24 NF, but I'm not sure, you will have to get the answer from an MRod guy....

I believe it is a 1/8 BSP (British Standard Pipe Thread) thread and seals using an O ring
Norm

so it is a tapered thread and the seal is just added insurance?
-
BSP threads are straight threads sealed by an O Ring

1/8 NPS at 27 TPI, no taper.
