American National Pipe Taper (NPT) threads American National Standard Pipe Thread standards, often called national pipe thread standards for short, are U.S. national technical standards for screw threads used on threaded pipes and pipe fittings. They are tapered thread series for various purposes including rigidity, pressure-tight sealing, or both. Firm: Heavy duty solid brass has strong corrosion resistance, thicker wall extends the service time, and brass pipe fittings are durable than iron and iron galvanized pipe fittings. Great fixation: Deeper and smoother threads allow better bite, enhancing fixation, not easy to slip. Tips: For better sealing, we suggest that all fittings must be used with sealing tape. These fittings contain lead and are not allowed by federal law to be installed for potable water use in the U.S.A. and its territories.
