  • Also called 'pipe taps', National Pipe Taper (NPT) taps are appropriate for threading a wide variety of materials both ferrous and non-ferrous.
  • The nominal size of a Pipe Tap is that of the pipe fitting to be tapped, not the actual size of the tap.
  • The thread tapers 3/4 of an inch per foot. All Pipe Taps furnished with a 2-1/2 to 3-1/2 thread chamfer.
  • 6 Piece Set of Carbon Steel NPT Pipe Taps, Sizes 1/8", 1/4", 3/8", 1/2", 3/4" and 1" in Wood Case

Most tap kits are only for machine bolts, course or fine thread. This kit is pipe thread and includes the most common industrial NPT fittings. I mostly work in steel, stainless steel and brass and these are Ideal for repairing threads. I would be careful trying to cut new threads but I would assume that the kit is plenty hard enough.

My husband says it works great. When he received the package the box was broken.

Well made and of good quality.
