Production Taps

NPT/ANPT and NPTF Spiral-Flute Production Taper Pipe Taps

Features and benefits
Features and Benefits:
  • Manufactured from select tap high-speed steel.

  • Ground threads standard in American Standard Pipe Form (NPT) and American Standard Dryseal Pipe Form (NPTF).

  • NPT threads require the use of a sealer, such as Teflon® tape or pipe compound.

  • NPTF dryseal threads give a pressure-tight joint without the use of a sealer.

  • Uncoated taps standard; coatings available as a stock modification.

  • Spiral flutes lift chips out of the tapped hole reducing stop lines.

  • Most effective in materials that produce long, stringy chips.
