    Alfa Tools 3/8″-18 HSS NPT Pipe Tap

    Part #: AL-HSNPT270304

    The Alfa Tools HSNPT270304 Pipe Tap is a premium cutting tool engineered for creating precise 3/8″-18 National Pipe Taper (NPT) internal threads in metal pipes, castings, and fittings. Manufactured from high-speed steel (HSS) for superior hardness and heat resistance, this pipe tap delivers long service life and consistent performance under demanding tapping conditions. Its tapered thread design produces a pressure-tight, leak-resistant fit ideal for fluid, air, gas, and hydraulic systems. Suitable for both hand and machine tapping, it conforms to ANSI/ASME B1.20.1 NPT standards, ensuring full compatibility with industry-standard pipe fittings and connectors.
