BSP Thread Types: BSPP vs BSPT

Understanding the distinction between the two types of BSP threads is crucial for ensuring a proper, leak-free connection.

  • BSPP (British Standard Pipe Parallel): These threads are straight or parallel. The seal is not made on the threads themselves. Instead, a BSPP male fitting features a 30° chamfered seat that perfectly mates with the 30° cone seat on a BSPP swivel female fitting. This design is commonly found on couplings and other applications requiring a swivel connection.
  • BSPT (British Standard Pipe Tapered): These threads are tapered. A pressure-tight seal is achieved on the threads when a BSPT tapered male is threaded into a BSPT tapered female fitting.

Important Compatibility Note

British Standard Pipe (BSP) threads are not interchangeable with American NPT, NPTF, or NPSM threads. The primary differences are the thread angle (BSP is 55° while NPT is 60°) and the thread pitch in most sizes. Always verify the required standard before ordering or attempting to connect fittings to prevent cross-threading and system failure.
