    NPT is National Pipe Thread, NSPT is National Straight Pipe Thread.

    I sent a carpenter down to the shop to get some 2-inch pipe threaded on the machine. I forgot that we own some straight thread dies in 1-1/2 and 2-inch NSPT. We use straight thread on lookout handrails, built from 1957 to 1961, when industrial railing was first specified.

    Any way, the Carpenter thought NSPT would mean National Standard Pipe Thread. And, made up a bunch of runs with that thread. Project took an extra day.

    Hi all.. I'm not sure if this is the right thread...
    I needed some help finding this type of connection...

    It is for a foot spa drain. 1 1/2" drain with very little clearance to the floor
