What is a 1/4 g thread?
Whitworth Parallel Pipe Thread DIN ISO 228 (DIN 259) BSPP (British Standard Pipe Parallel)

Is G thread same as NPT?
The G (BSP / BSPP) standard is used in Europe and around the world. Although the threads look incredibly similar, they are not compatible. The NPT (US Standard) thread is tapered with a 60 deg thread pitch and designed to seal when the threads compress together, with pipe tape to fill in any minor leak paths.
Is BSP the same as Whitworth?
BSP threads have rounded valleys and troughs with a 55 degree pitch (this is known as Whitworth type). There are two types of BSP threads; Tapered (BSPT) and parallel (BSPP). The vast majority of BSP threads for water fittings are parallel.

What is G thread and R thread?
BSP distinguishes between two types of threads. These are parallel threads (BSPP), which have a constant diameter, which are known a G threads, and taper threads (BSPT), whose diameter increases or decreases along the length of the thread, known as R threads.
What does G stand for in threads?
Two types of threads are distinguished: Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP; originally also known as British Standard Pipe Fitting thread/BSPF and British Standard Pipe Mechanical thread/BSPM), which have a constant diameter; denoted by the letter G.
What is R thread type?
R = External tapered screw pipe thread for fits made on the thread per ISO-7 & BS-21. Per the standard the R mates with the Rc and Rp, but will also mate with the G. Rc = internal tapered threads for fits made on the thread per ISO-7 & BS-21. Per the standard Rc mates with R.
What is an R thread?
These are parallel threads (BSPP), which have a constant diameter, which are known a G threads, and taper threads (BSPT), whose diameter increases or decreases along the length of the thread, known as R threads.
Is R thread the same as NPT?
NPT threads are common in the United States and a few other countries, BSP threads (also know as the R subset according to ISO 7) are widely used in many other countries.
