As we know, the male NPT fitting can screw into a female NPT thread. this process could be discribe like this: tighting the fitting for several turns with hand, and then tighting the fitthing for several turns by the wretch. Here I have a question: what is the tolerance of the engagement of the coupling?how can we control the screwed depth? by torque or anything?
