What does G mean in thread?
G (supposedly from German/English “Gas”) are the cylindrical pipe threads used on originally inch based pipes. The internal (conical) pipe thread is is described as “GCon”. The size designation (like 3/8″) does not mean actual thread OD; it is the internal diameter of the pipe, on which it is used.
What is the 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.
What r1 8 thread?

What RC1 8 thread?
Tapered Pipe Thread Plug Gauge (RC1/8-28P) A tapered screw gauge used for inspection of screws (R, Rc, Rp) primarily for mechanical connections that require sealing, newly established by JIS after introduction of the ISO gauge standard.
What is ISO R thread?
ISO Metric thread is a globally standardized thread. Compared to standard threads (coarse thread), a fine thread has a smaller pitch. The flank angle is 60°. Female and Male thread are both parallel. NPT and NPTF appear to be identical.
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.
