High quality brass adapter fitting 1/8 NPT Male to 1/8 PT (BSPT) Female. Female: 1/8 PT (BSPT - 1/8"-28). PT and BSPT thread type are interchangeble. Chinese gauges/sensors/adapters tend to use 1/8 PT thread, so if you have a Japanese gauge/sensor/adapter to fit into a Chinese sensor thread (be it a water pipe fitting, oil sandwich plate or anything else) then this will allow that.
