Drill size w/out. taper pipe reamer. Straight pipe. threads. 1/16. 27. 15/64. 1 NPT refers to nominal inside pipe size. I don't have my tap chart handy, so I'll use an example, A fitting of ~1" ID and 1/8" wall would be 1-1/4" OD. If this were a straight thread, minor dia. would be 1.156" and Major dia would be a hair over 1-1/4. Then consider that this is a tapered pipe thread..
