    Thanks everyone but it’s 3/8 x 27tpi that I need – not 1/8

    1/8″ NPT is a tapered pipe thread. 1/8″ SCH 40 pipe is 0.405″ outside diameter the plug, being tapered and threaded will be in the neighborhood of 3/8″ nominal O.D. I believe that is what you are going for. 3/8″ SCH 40 pipe would have an O.D. of about 0.675″.
