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

so it is a tapered thread and the seal is just added insurance?

BSP threads are straight threads sealed by an O Ring
