BSP - British Standard Pipe (BSPP Parallel & BSPT Taper) |
|
|
The British BSP connections include two types of thread, BSPP which are straight (or parallel) and BSPT which are tapered. The BSPT tapered male will mate with a BSPT tapered female (usually a port) and seals on the thread. The BSPP parallel male has a 30° chamfered seat which seals with a BSPP female on its 30° cone seat. |
