NPT threads are for mechanical or low-pressure air or fluid applications and require the use of sealing compounds like Teflon tape, to provide the seal. When the application is more critical, and the sealing compound may fail due to high heat or pressure, NPTF Dryseal threads are used.

Difference Between NPT and NPTF: Function: NPT is general-purpose tapered pipe thread. On the other hand, NPTF is a dry seal tapered pipe thread. Thread Crest: Generally, both thread crests have the same parameter requirements. However, NPT has a larger range. Thread Root: The design of NPT thread roots allows clearance with mating thread crests on assembly.

NPT threads are used in mechanical or low-pressure air or fluid applications and the use of sealant or tape is adequate to prevent leakage. NPTF taps are made to different specifications so that in addition to sealing on the flanks of the thread like the NPT form, the threads also seal at the joining of the crest and root of the assembled threads eliminating the possibility of leakage.

Apr 08, 2019 · Both NPT and NPTF have the same threads-per-inch, pitch diameters, and taper-per-inch. The differences come in the major and minor diameters, the root and crest of the threads. The NPTF thread crests fall with in the parameters of the NPT requirements, but have a smaller range than the NPT.

NPT (National Pipe Taper) is a general-purpose tapered pipe thread, and NPTF (National Pipe Taper Fuel) is a dryseal tapered pipe thread. Visually, NPT and NPTF pipe threads look identical. Both thread types rely on thread interference for tight, robust connections. This thread interference is made possible primarily by their tapered design.

While NPT and NPTF are both designed to screw together, NPT requires a seal to be leak proof while NPTF do not. The L1 gauge requirements for NPT and NPTF differ for threads more than ½ in. in size, and thus, are not interchangeable. The difference lies in the Plug Gage Major Diameter and Ring Gage Minor Diameter.
