JIS Tapered Pipe Thread (PT)

 JIS Tapered Pipe (PT) has metric threads per JIS B 0203. These are JIS tapered threads and are comparable to the design of BSPT fitting connections in their dimensions and appearance. JIS tapered thread connections are interchangeable with BSPT connections. However, the male end does not have a 60° chamfer and will only seal when the threads are crushed together in an appropriate JIS or BSP port
