Hi Joey, mnpt stands for Male National Pipe Thread Taper (MNPT), sometimes called NPT or MPT. It means the threads are on the outside of the connector. ... As others have said, it means Male National Pipe Thread, which is a Standard.

How is NPT size?
As a general “rule of thumb” an NPT thread is approximately 1/4" (0.25”) larger than its “name.” For a 1/4" NPT fitting the “nominal” OD is 0.533”. NPT fittings are slightly tapered so the “nominal” diameter is the diameter in the middle of the threaded portion, as measured by the top (crest) of the threads.Jun 13, 2018
What is the diameter of 1 NPT?
How do you measure NPT threads?
To determine the NPT size, with a caliper, measure the diameter of the 2nd or 3rd thread on your pipe, fitting or valve as shown below. Find the caliper measurement in the chart and cross reference the nominal NPT pipe size. Don't get confused, the actual measurement is not the same as the NPT pipe size.

What is OD and NPT?
NPT fittings are listed by the "standard" inner diameter (I.D.) of the fitting. ... The outer diameter (O.D.) of the threads is usually about 1/4 (0.250) in. larger than the stated I.D. size. This measurement will also vary, depending on where you take the measurement.Jun 17, 2017
What is MPT and FPT?
MPT and FPT are simply names for identifying the type of pipe thread for an application. MPT and FPT are both sub-types of NPT. National Pipe Threads (NPT) have tapered threads. NPT threads are used for joining and sealing pipe fittings in low pressure air or liquid applications.
What does NPT fitting?
NPT stands for National Pipe Tapered threads, also known as ANSI/ASME B1. 20.1 pipe threads. It is a U.S. standard for measuring tapered threads on threaded pipes and fittings. ... Unlike straight threads found on a bolt, a taper thread will pull tight, making a closer seal.Apr 19, 2016
