Dry seal thread NPTF allows for joining without sealants NPT threads may be designated as quot FPT quot Male NPT threads may be designated as quot MPT quot The pipe size is often written such as this 1 8 quot 27 with a hyphen between size amp thread per inch and pronounced as quot one eighth twenty seven quot
NPTF National Pipe Thread Tapered Fine also called Dryseal American National Standard Taper Pipe Thread is a U S standard for tapered threads used to join pipes and fittings is defined by ANSI B1 20 3 For NPT threads a sealant compound or Polytetrafluoroethylene PTFE tape must be used for a leak free seal
Steel Pipe Thread NPTF Fittings NPTF National Pipe Tapered Fuel thread seals when the male taper mates with the taper crushing the thread and creating a mechanical lock It is recommended to use Teflon tape or pipe thread sealant to prevent leakage Pipe fittings are uniform across most manufacturers and are equivalent to fittings
Dec 22 2015 nbsp 0183 32 For the National Pipe Tapered for Fuels or NPTF the pipe should be thread as per ANSI B1 20 3 Differences in NPT and NPTF threads lie in the major and minor diameters as well as the root and crest of the threads NPTF thread crests call within the same parameters as NPT requirements but NPTF crests have a smaller range
For example a 3 4 quot NPT pipe thread has an outside diameter of 1 050 inches Each thread size has a defined number of threads per inch TPI The 3 4 quot NPT pipe thread has 14 threads per inch Both the TPI threads per inch and OD outside diameter of the thread are required for positive identification of thread size because several sizes

Metric button head couplers are designed to grease metric button head fittings with head diameters listed in the chart below Metric button head couplers have a smaller clearance than traditional couplers which provides a tighter seal around metric button head fittings
The NPSM thread design differs from the NPTF pipe thread design which seals on the threads themselves The NPSM pipe swivel seals on a 30 176 seat flare and is visible down inside of the swivel nut This swivel nut is permanently attached to the body and mates with a male pipe thread that has a 30 176 seat chamfer machined into the end

As with NPT threads the nominal size does not represent true outside pipe diameter but in the larger sizes it comes very close Sizes start at 1 16˝ and go up through 6 inches Note there is no ISO thread modification such as the NPTF National Pipe Thread Fuel for improved sealing between threads Usually a thread sealant is required
