Quality carbon steel BSP threaded pipe fittings are highly in demand, which are available in sizes of 1/8", 1/4", 3/8", 1/2", 1/4", 1", 1 1/4", 1 1/2" and 2" with pressure of 2000lb, 3000lb, 6000lb according to ASME B16.11.
BSP thread form stands for British Standard Pipe and is common in Australia and the commonwealth countries. It is based on trade size rather than actual diameter which can lead to some confusion when measuring ports.
There are two types of BSP threads;
- Parrallel (BSPP) - also known as G or Rp
- Tapered (BSPT) - also know as R or Rc
Both threads have the same pitch, angle (55 degrees) and shape (rounded peaks and valleys).
