Product Description
Also called pipe taps, carbon steel NPT pipe taps are designed to clean and or re-thread damaged or jammed pipe threads. They are appropriate for threading a wide variety of materials both ferrous and nonferrous. 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 NPT threads require the use of a sealer like teflon tape or pipe compound.
