British Standard Pipe (BSP) can be most commonly found in Canada, UK, Europe, Asia and Australia. It is a finer thread than National Pipe Thread (NPT), and will not seal properly if used in conjunction with it. Two types of threads are used:
- British Standard Pipe Taper (BSPT) and British Standard Pipe Parallel (BSPP). British Standard Pipe Taper uses a tapered thread system, and sealant is provided to help secure the male and female connection.
- British Standard Pipe Parallel uses a parallel thread system, and a rubber gasket is often included to secure the male and female connection.
