Are BSP and NPT interchangeable?

Are BSP and NPT interchangeable?

NPT and BSP threads are generally not compatible due to the differences in their thread forms. NPT and BSP thread pitches (threads per inch, TPI) are listed below. You can use 1/2″ and 3/4″ NPT and BSP fittings together, but all others will be incompatible and will therefore leak.

What is the difference between BSP and NPT?

Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes. With NPT, the peaks and valleys of the threads are flat. In BSP, they are rounded. Secondly, the NPT angle of the thread is 60 degrees and the BSP angle is 55 degrees.

Are BSP and G threads the same?

Is G thread the same as BSPP? The two types of thread are the same parallel straight. BSPP is the British Standard Pipe Parallel thread and it is also denoted by the letter G (ISO standard). Therefore, BSPP is the same as G.

What is BSP fitting?

British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread.

Is UNF compatible with NPT?

Most North American hydraulic and pneumatic components are compatible with National Pipe Threads (NPT), or Unified Threads (UN/UNF).

Is BSP tapered?

The British BSP connections include two types of threads, BSPP which are straight (or parallel) and BSPT which are tapered. The BSP threads are similar to, but not interchangeable with American NPTF pipe threads.

What does NPT mean in piping?

National Pipe Tapered Thread
The best known and most widely used connection where the pipe thread provides both the mechanical joint and the hydraulic seal is the American National Pipe Tapered Thread, or NPT. NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.

Will BSPP male mate with BSPT female?

The BSPT (tapered) male will mate with a BSPT (tapered) female, or a BSPP (parallel) female. The BSPT connector is similar to, but not interchangeable with, the NPTF connector. The thread pitch is different in most cases, the thread angle is 55° instead of the 60° angle found on NPTF threads.
