NPTF (National Pipe Taper Fuel) threads are a dryseal version of the NPT (National Pipe Taper) threads, designed to provide a more leak-free seal without the need for additional sealing compounds. The specifications for NPTF threads are governed by ANSI/ASME B1.20.3, which details the dimensional and tolerance requirements to ensure proper sealing and compatibility with other NPTF fittings.
