    These locknuts have the strength to handle high-pressure applications. They are brass for good corrosion resistance.
    Locknuts thread onto the male end of a fitting to provide extra holding power so the fitting won’t loosen from vibration.
    NPTF Thread—NPTF (Dryseal) threads are compatible with NPT threads.
