Connections Using British Standard Pipe (BSP) Threads

British Standard Pipe is most commonly used as British Standard Pipe Parallel (BSPP), sealed with a 60o cone seat (solid male British) standard pipe is most commonly used in ports, using a rubber or copper washer seal. BSP flat face is BSPP thread with a flat surface at the nose of the thread for sealing. This is most commonly used on HIAB equipment. BSP male threads may also be tapered ( BSPT), and can be used in either BSPP female or BSPT female ports with a suitable thread sealant. BSPT is commonly used on Japanese equipment and is part of the JIS standard. BSP thread size are listed in the following tables :
