Whitworth Pipe Threads
Using Whitworth pipe threads it has to be distinguished between those threads which are thought to be sealing on the
thread and those which produce a mechanical connection without sealing function.
Those threads which are sealing on the thread are specified in various national and international standards. Basic
thread dimensions are common for all threads mentioned below. ISO 7/1 and BS 21 do not only specify the connection
of cylindrical internal and taper external thread as DIN 2999 does, but in addition define a taper internal thread (taper
1 : 16). Gauging systems for all three threads differ and may lead to different results and decisions.
The thread connection given in DIN ISO 228 is not
meant to be sealing on the thread. Basic thread dimensions
and pitch is common to the sealing threads.

NPT „general purpose” taper taper
NPTF dry sealing taper taper
NPSC C=coupling „general purpose” taper (NPT) cylindrical profile as NPT
NPSM M=mechanical fastening thread cylindrical cylindrical UN-thread profile
NPSF dry sealing taper (NPTF) cylindrical profile as NPTF
NPSI dry sealing taper (NPT-SAE / cylindrical thread diameter slightly increased with,
NPTF) same width of tolerance field
NPSL L=Locknut cylindrical cylindrical
The difference between thread profile of NPT and NPTF threads is the width of flat of profile on the outside and minor
diameter. NPTF thread has got an overlap of profiles of internal and external thread. By this method, drysealing
property is achieved. Compared to the NPT, NPTF is one thread longer on L1 + L3 and L2.
NPT-, NPSC-, NPSM- and NPSL-thread are defined in ANSI/ASME B1.20.1, NPTF, NPSF and NPSI-thread are given in ANSI B1.20.3
