    NEMA Standards Publication FB & threads on 1/2" compression connector

    Greetings does anyone on here happen to have access to NEMA Standards Publication FB or know what the standard threads on 1/2" compression connector are?
    Not the standard 1/2" NPT thread but the thread on the gland nut of a coupling.
    Thanks

    I believe it is a 7/8-18-2A UNS thread based on the drawing for a compression offset connector on page 94 at:

    The drawing for a straight compression connector doesn't show the thread size but it's likely to be the same.
