NPT Full Coupling 4" for Hot dip galvanized pipe X42
Common American National Standard Pipe Taper Threads
NPT - National Pipe Thread Taper
NPTF - Dryseal American National Standard Taper Pipe Thread (ANSI B1.20.3)
NPT threads may be referred to as MPT ('Male Pipe Thread'), MNPT, or NPT(M) for male (external) threads, and FPT Common American National Standard Pipe Taper Threads
a) NPT - National Pipe Thread Taper
b) NPTF - Dryseal American National Standard Taper Pipe Thread (ANSI B1.20.3)
NPT threads may be referred to as MPT ('Male Pipe Thread'), MNPT, or NPT(M) for male (external) threads, and FPT ('Female Pipe Thread'), FNPT, or NPT(F) for female (internal) threads. Note that FPT and MPT are not authorized designations per the ANSI standard.
Characteristics of NPT (also known as ANSI/ASME B1.20.1 Pipe Threads, General Purpose):
the angle between the taper and the center axis of the pipe is 1o 47' 24'' (1.7899o)
truncation of roots and crests are flat
60o thread angle
pitch is measured in threads per inch
Note! Pipe sizes do not refer to any physical dimensions. The outside diameter of a pipe or fitting must be measured and co***red to a table for size identification. A 3/4" NPT pipe thread has an outside diameter - OD - of 1.050 inches.
Each thread size has a defined number of threads per inch - TPI, or pitch. The 3/4" NPT pipe thread has 14 threads per inch. Both the TPI and OD of the thread are required for positive identification of thread size because more than one size have the same TPI.
For NPT threads a sealant compound or Polytetrafluoroethylene (PTFE) tape must be used for a leak-free seal. For NPTF no sealant is needed for a leak tight connection.
