There are two types of BSP Thread available. One is Parallel threads or we can say Straight threads. The second one is the Taper Thread. BSP is BRITISH STANDARD PIPE THREAD- Also known as Whitworth 55° Thread Form. BSPT is BRITISH STANDARD PIPE TAPER THREAD - Thread form per AS 1722.1, BS 21, ISO 7.

R series thread plug gages, both Rc (BSPT) and Rp (BSPP), G-GR-LD are designed to inspect the pitch diameter and functional thread for internal-thread components. All plug gages are available with Certificate of Accuracy documentation. Both tapered and staight R series threads use the same gages to inspect per DIN EN 10226-3, ISO 7-2.

Explanation: Pitch: Designated by "X P". For example, M8 X 0.75 means an 8 mm (0.315″) thread with a pitch of 0.75 mm (0.03″ or 34 TPI).If the "X P" is omitted, the pitch is defined by the Coase Pitch Series according to ISO-261. Number of starts: Designated by "Ph".For example, M8 X Ph2.25P0.75.In this case, 2.25 mm is the lead, and 0.75 mm is the pitch.

Answer】. The size and number of threads are the same but application is different. In other words, the Rp(PS) is used for preventing water and gas

You will see under tapered pipe thread some Rc inch specifications and under straight pipe thread some Rp inch specs.

Diameter and pitches are the same for ISO 7-1 and ISO 228 threads. ISO 7-1 is BSPT (R/Rp) - British Standard Tapered Pipe where R - tapered male with external threads Rp - cylindrical with internal threads Rc - tapered with internal threads G-threads have a parallel shape in accordance with the DIN-EN-ISO 228-1 standard.

Example: metric thread diameter 7 with a pitch of 1 mm = M7x1. There are two types of "Pipe" profile threads: • Parallel (BSPP): these threads fit in matching

Thread sizes are based on trade size rather than actual dimension, R, Rp and Rc threads are taken from BS21:1985 pipe threads for tubes 

For metric threads, this tool measures the distance between the threads. If you're looking to buy a thread pitch gauge, Grainger has a pretty good selection. How to Identify Different Types of Threads Step 1 - Male Threads v. Threads First, you'll need to identify whether the thread type is male or female.

BS EN 10226-1. When designating threads to this standard three blocks are require: Block 1 (Pipe Thread): Block 2 (International standard ref = EN 10226: Block 3 R (size) For external taper thread: or Rp ( size) For internal parallel thread. Example external taper thread designation

A male G thread and G thread together do not have sealing effect, it is mainly used in wire tube / cable tube which do not require sealing effect. (2) Sealing pipe thread, these kinds of thread have sealing effect after screwed. There are three types of sealing pipe threads: R thread: tapered male thread. Rc thead: tapered thread.
