Taper Pipe Thread Gauges

Taper thread ring gauges and taper thread plug gauges are used to check wheter a taper external thread (pipe) and a taper internal thread (pipe joint) which have been screw-cut for pipe connection can achieve a satisfactory fit.
When the taper thread gauge is fitted in the taper thread being inspected by hand-tightening, it will always stop.
It is possible to judge the dimensional accuracy of the thread in a comprehensive manner by checking the gauge stop position to measure the axial gauge travel.
