BSPP/BSPT: BSP stands for British Standard Pipe, can be divided into BSPP (parallel, Thread form per AS 1722.2, ISO 228) and BSPT (taper, Thread form per AS 1722.1, BS 21, ISO 7). BSPP threaded fittings do not require sealants, and use banded seal rings to seal fittings in between the shoulder on the male and the face of the female,
1-1/4" BSP - Wash hand basin (bathroom sink) wastes. 1-1/2" BSP - Kitchen sink wastes, bath wastes, toilet syphon outlets, central heating pumps. 2-1/4" BSP BSP - Immersion water heater elements. The BSP to mm conversion chart below shows metric and imperial dimensions for male threads and the number of threads per inch (TPI) :

BSPT (British Standard Pipe Taper) is similar to NPT but there are a few important differences. 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. Another important difference is that for many BSPT pipe sizes
BSPP é rosca paralela / whitworth, BSPT, R e RC é rosca cônica, mas RC é rosca fêmea BSPT. BSPP e BSPT (na maioria dos casos) têm diferentes threads por polegada (TPI) (e, consequentemente, pitch). A rosca macho BSPT do atarraxamento acopla-se a uma rosca fêmea BSPT ou BSPP, portanto, esta situação pode ser
While NPT/NPS threads are common in the United States and Canada, BSPT/BSPP (collectively, BSP) threads are widely used in many other countries. I have found that my Japanese-built injection mold presses have predominantly BSP fittings. BSPT -British Standard Pipe Taper BSPP -British Standard Pipe Parallel NPT -National Pipe Taper
BSP parallel (BSPP) threads commonly seal via a 30° chamfer on the male thread to a 30° cone seat inside the female thread (swivel only). If it is a port application, an O-ring and washer, Elastomeric seal or a bonded washer are needed to achieve a proper seal for parallel threads. For tapered BSP threads (BSPT), a seal is accomplished via
Estándar europeo: BSP. Rosca BSPP o Gas. Empezamos hablando de las roscas BSP, que como decíamos en la introducción, son roscas de sistema Whitworth y por lo tanto basadas en una rosca con ángulo de 55 grados.Es el estándar que se ha adoptado en todo el mundo (excepto en norte América) para la conexión y sellado de
