Determination - Thread Types G or R or BSP G or R (Whitworth) or BSP (British Standard Pipe) Thread Cylindrical threads which are mainly used in countries with imperial system. The size of e. g. R 3/4" does not stand for a diameter. Thus the corresponding size has to be determined according to charts.

There are two types of BSP threads; - BSPP - male thread are both (also known as G) - BSPT - thread is parallel and the male thread is tapered (also know as R/Rp) (the thread can also be tapered it is then Rc, these are fairly rare to find).
