    Description

    NPTF...National Pipe Taper Fuel
    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. The use of an NPTF marked tap for NPT applications is appropriate, however NPT taps cannot be used for dryseal (NPTF). When visually comparing these two styles in the same size they look identical. Both have a ¾” taper in 12 inches of length and at the top of a threaded hole the pitch diameters are the same, the variation is in the crest and root specifications of the NPTF tap.
    2 5/8 inches long.
