Creates G1/4-19 55-degree taper pipe threads using a 13.5mm HSS four-flute tap with 26mm thread length and 65mm overall length

  • Creates precise pipe threads with 55 degree taper angle
  • Four-flute HSS design cuts cleanly through metal piping
  • 5mm flute diameter matches G1/4-19 thread standard
  • 26mm thread length provides full engagement depth
  • 65mm overall length fits standard tap wrenches and holders

Thread tap compatibility

This G1/4-19 thread tap suits mechanics and fabricators who need to cut 55-degree taper pipe threads in metal components. The HSS construction provides wear resistance for general workshop use. It is not for buyers who require straight-thread taps or metric pipe threads, nor for jobs needing a larger or smaller nominal diameter than the G1/4 size.

Critical specification

The 55-degree taper angle and 19 threads per inch pitch determine whether this tap matches the thread standard required for the application. These two values must correspond exactly to the fitting specification; otherwise the threads will not seal correctly.
