The ISO 7 tapered Whitworth threads are equivalent to DIN 2999, BS 21 (BS EN 10226-1), JIS B0203. This part of ISO 7 specifies the requirements for thread form, dimensions, tolerances and designation for joining pipe threads, sizes 1/16 to 6 inclusive, for joints made pressure-tight by the mating of the threads. The British standard pipe thread (BSP thread) is a family of standard screw thread types . that has been adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal (female) thread. Tapered male pipe fittings (courtesy Swagelok) . . Rc - Inch sealed taper thread. Tube and pipe are hollow structures designed to provide a path for the flow of fluids or gases. The angle across the flanks of threads (if you sliced the fitting in half long-ways and measured the angle from root to crest to root) is 55 degrees instead of 60 degrees as it is for NPT . This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. Competitor's Part Number. BSPT external thread and BSPT non-adjustable internal thread seal.

And BSPT is a taper thread, it creates a seal by thread. in inches, but with a slightly different thread . In the same fashion as the straight threads, you can either measure the tapered profile, or simply observe the decreasing diameter of the threads. BSPT (British Standard Pipe Taper) is similar to NPT except there are important differences. The below table gives the major and . BSPP vs BSPT vs R and Rc thread are different applications of adapters. BSP tapered threads. BSPP is parallel thread, BSPT, R and Rc are taper thread, but Rc is female BSPT thread. Equivalents.
