What is G in thread size?
Whitworth Parallel Pipe Thread DIN ISO 228 (DIN 259) BSPP (British Standard Pipe Parallel)
| Nominal Diameter | Major Diameter Inch | Pitch mm |

| G 1 1/8″ | 1.492 | 2.309 |

Are G and R threads compatible?
Male G-thread (parallel) can only be screwed into female G-thread. Male R-thread (conical) can be screwed into a G or R thread. The following table shows the internal minimum thread diameter, with upper deviation.
Is RP same as G?
Both have the matching size designations (nominal major diameter and threads-per-inch). The differences between the G-series screw thread and the Rp-series screw thread include: The G-series screw thread is made to ISO-228 while the Rp-series screw thread is made to ISO-7 or BS-21 or EN 10226-1.
What does R mean in 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 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.
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.
What is difference between R and G 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.
Is G thread same as R thread?
What does RP thread mean?
The Rp thread is a designation for BSPP (British Standard Pipe Parallel). For example, Rp 1/4. refers to the threaded end of a fitting or pipe which is 1/4 inch trade size (not actually 0.25 inches), and having British Standard Parallel Pipe threads.
What does RC thread stand for?
Internal Taper
Rc – Internal Taper (ISO 7) Rs – External Parallel.
What is the difference between R and RC threads?
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 are the 3 basic types of threads?
There are three standard thread series in the Unified screw thread system that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).
Can you use NPT in G thread?
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 G thread a BSP?
G & R Thread Types
G is the international standard shorthand for BSPP – BSP Parallel threads. R is the standard for BSPT – BSP Tapered.
What does G1 2 thread mean?
Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP). These are sometimes denoted by the letter G, for example G1/2″ means a parallel 1/2 inch BSP thread. Taper threads, British Standard Pipe Taper thread (BSPT).
What is the difference between R and G threads?
What are G type threads?
G (BSP / BSPP) thread is parallel with a 55 deg thread pitch and designed to seal with a Bonded washer seal (included with our fittings) or an O-ring face that may be machined into your fixture.
How do you determine thread size?

What is 2A and 2B in threads?
Classes 2A and 2B are by far the most popular thread classes specified for inch series mechanical fasteners. Close to 90 percent of all commercial and industrial fasteners produced in North America have this class of thread fit. Class 2A external threads have an allowance, Class 2B internal threads do not.
What is G type thread?
G connections have a straight body (constant diameter) with parallel (straight) threads. The main purpose of the parallel threads is to contain the pressure, which allows for regular installations and removals without damaging the thread. A sealing washer is required to seal the connection.
What is R thread and G thread?
Are G and BSP the same?
The two types of thread are the same parallel straight. BSPP is the British Standard Pipe Parallel thread and it is also denoted by the letter G (ISO standard). Therefore, BSPP is the same as G.
What size is G 1 2 thread?
1/2 inch
Parallel (straight) threads, British Standard Pipe Parallel thread (BSPP). These are sometimes denoted by the letter G, for example G1/2″ means a parallel 1/2 inch BSP thread.
