Stewarts - High Tolerance NPT Thread

Stewart-Buchanan High Tolerance NPT Thread goes over and above the normal tolerances of a standard NPT thread. Using current tapered thread standards, Stewarts have maximised the tolerance on the male thread while minimising the tolerance at the female end. This means that the NPT connection has five to six threads engaged when fully tightened compared with the usual three to four threads of a standard NPT connection.
