BSPT - British Standard Pipe Taper Thread Ring Gauges
The British Standard Pipe (BSP) technical standards for screw threads has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread. It has been adopted as standard in plumbing and pipe fitting. BSPT is also known as R (external thread) and Rc (internal thread), with 1:16 taper thread. It has a pitch angle of 55°.
R ISO-based JIS
Taper pipe threads (R) specified in JIS are used to connect fluid equipments, plumbing parts, pipes where density resistance is necessary for their mechanical connection. The Ojiyas gauges for taper pipe threads (R) are used for inspecting the dimension of such the threads.
PT Conventional JIS
Taper pipe threads (PT) specified in JIS are used to connect fluid equipments, plumbing parts, pipes where density resistance is necessary for their mechanical connection. The gauges for taper pipe threads (PT) are used for inspecting the dimension of such the threads.
Note:
Female parallel pipe threads are used for male taper pipe threads. Their limit deviation tolerances are different from the female parallel pipe threads (G) or (PF).

Ojiyas Taper Pipe Threads
The taper thread plug gauge is used to inspect the coupling between the male taper thread and the female taper thread.
The gauge should stop when it is fitted to the threads to be inspected.
According to conventional JIS (PT), the female taper thread is passed when the inserted taper thread plug ① stops within the range of notch 2c. Similarly, the male taper thread is passed when the inserted taper thread ring ② stops within the range of notch 2b. In the case of taper thread plug (R) ISO-based JIS ③, the female taper thread is passed when the end of inserted taper thread plug stops within the range of T2. And the male taper thread is passed when the inserted taper thread ring (R) ④ stops within the range of T1. The inspection plug (CP) ⑤ is used to confirm whether the effective diameter of taper thread ring (R) ④ exceeds the specified wear limit.
