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 is a G1 2?

G1/2”x15mm Compression Fitting WRAS approval. Compression fittings offer a convenient way to connect gas or water pipes. Make sure that the pipe is cut straight and that it is free of burrs and sanded smooth. To cut a pipe straight it can be useful to use a pipe cutter.

What are the tolerances for internal G thread pitch diameter?

The tolerances on the pitch diameter of the internal G-threads correspond to the ‘positive’ deviation of the diameter tolerances in ISO 7-1, with the exception of those for thread sizes 1/16, 1/8, 1/4 and 3/8, for which slightly higher values are specified. INTERNAL G-THREAD RP-THREAD

What is the difference between g1/8 and R1 8 thread sizes?

In the case of a thread of size 1/8”, for example, the threads are specified as G1/8 or R1/8. Male G-threads (parallel) can only be screwed into female G-threads. Male R-threads (tapered) can be screwed into female G or R-threads.

What does g1/8 mean on a screwdriver?

What is the pitch of a thread?

The pitch is the distance from the crest of one thread to the next in mm. TPI (Threads per inch) is used by inch thread. DIAMETER: The major diameter is determined by the thread tips.
