    NPTF Thread

    Verify whether pipe fitting threads fall within tolerance. These gauges are attached to a handle, giving you a solid gripping point to thread and unthread them quickly. All are precisely manufactured to tight thread tolerances. If the gauges wear down, you can install new ones (not included) on the taperlock handle.
    NPTF Thread—Gauges with NPT, NPTF, and BSPT threads have a notch to indicate whether the threads you’re checking are within tolerance. If it takes no more than one turn for the notch to sit flush against the end of your fitting, the threads are within tolerance.
    Plug Gauges with Calibration Certificate Traceable to NIST—Gauges with a calibration certificate traceable to NIST were calibrated in a lab. The certificate, sometimes called a test report or long-form certificate, details the tested measurements.
