The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

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.

The table below summarises BSP sizes to help with general identification. Major diameter is slightly less than the actual outside diameter of the threads.

For example, G threads are not compatible NPT threads because of their differing angles, shapes, and thread Metric Thread Type Chart.

The most common types of Whitworth thread are: BSPP (G) – British Standard Pipe Parallel; BSPT (R/Rp) – British Standard Tapered Pipe, for pipes and tapered 

Taper threads, British Standard Pipe Taper thread (BSPT), whose diameter increases or decreases along the length of the thread; denoted by the letter R. The 

per inch, while a 1/4-28 (UNF fine) thread has the same nominal major diameter but 28 threads per inch. Metric thread specifications are different because the thread pitch is defined by the distance between each thread in mm instead of threads per inch. For example, an M12x1.75 (coarse) thread has a 1.75mm pitch, while an M12x1.50 (fine) thread

Parallel (G) threads are used where the seal is made on a mating face, like inside a cast iron radiator with the aid of a gasket. Tapered fittings achieve a

Whitworth's new standard specified a 55° thread angle and a thread depth of 0.640327p and a radius of 0.137329p. Where p is the pitch. The thread pitch increases with the diameter in steps specified on a chart. The Whitworth thread system was later to be adopted as a British Standard to become British Standard Whitworth (BSW).

These pipe threads are also known as Whitworth pipe threads. Where: D = Major Dia.internal thread D 1 = Minor Dia.internal thread D 2 = Pitch diameter internal thread

No thread sealant is needed to form a seal. G (supposedly from German/English “Gas”) are the cylindrical pipe threads with 55°apex angle used on originally inch based pipes.
