General purpose Pipe Taps are appropriate for threading a wide variety of materials both ferrous and nonferrous. Ground Thread Pipe Taps are standard In American Standard Pipe Form (NPT) and American Standard DrySeal Pipe Form (NPTF). NPT threads require the use of a ""sealer"" like teflon tape or pipe compound. DrySeal taps are used to tap fittings which will give a pressure tight joint without the use of a sealer. 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 2-1/2 to 3-1/2 thread chamfer.
