Example for 1 2 14 NPT external pipe thread L2 should be 0 5337 The maximum allowed variation is 0 5337 0 003 0 0016 0 04 mm Since the pitch is 14 TPI this is equivalent to 14X0 5337 7 47 thread turns Hence turning the thread 7 times should advance it along its axis by 7 14 0 5 and the allowed tolerance is 0 003X0 5 0 The taper rate for all NPT threads is 1 16 3 4 inch per foot measured by the change of diameter of the pipe thread over distance The angle between the taper and the center axis of the pipe is 1 47 24 1 7899 Commonly used sizes are 1 8 1 4 3 8 1 2 3 4 1 1 1 4 1 1 2 and 2 inch appearing on
