The term “BSPP” stands for British Standard Pipe Parallel. It is a type of thread standard used in pipe fittings and connectors, particularly in the United Kingdom and various other countries that follow British standards.
BSPP threads are parallel threads, meaning the threads run straight and do not taper. This is in contrast to tapered threads, such as those found in NPT (National Pipe Thread) fittings commonly used in the United States. The parallel nature of BSPP threads allows for a tighter and more secure seal.
The BSPP thread standard uses a cylindrical shape with a 55-degree thread angle. The thread pitch is measured in threads per inch. For example, a common size for BSPP threads is G1/4″, where “G” stands for parallel thread and “1/4” refers to the nominal size of the thread.
BSPP (British Standard Pipe Parallel) threads follow a specific set of dimensions. Here is a chart outlining some common BSPP thread sizes:
It’s important to be aware of thread standards when working with pipes and fittings to ensure compatibility and proper sealing. Mixing different thread standards can lead to leaks and other issues.
