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.

BSPT (R/Rp) – British Standard Tapered Pipe, for pipes and tapered thread. tolerances in ISO 7-1, with the exception of those for thread sizes 1/16,.

There are two types of BSP threads; - BSPP - male thread are both (also known as G) - BSPT - thread is parallel and the male thread is tapered (also know as R/Rp) (the thread can also be tapered it is then Rc, these are fairly rare to find).

R (Rp, Rs, Rc, R1, R2) - Inch taper pipe threads (standard: BS 21, BS EN 10226-1, ISO 7-1, DIN 2999) R thread Specifically as follows: Rp - Inch sealed cylindrical internal thread. Rs - Inch sealed cylindrical external thread. Rc - Inch sealed taper thread. R1 - Imperial seal cone external thread, and Rp with the use of, that is, Rp/R1 "column

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.

The G-series and the Rp-series British Standard Screw Threads have much in Below is a chart displaying the G1” effective pitch diameters 

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 

These metric pipe thread sizes have been adopted by the ISO (International Internal parallel threads: “Pipe thread ISO 7/1-Rp 1½˝ (for example).

Use a caliper to measure the nominal male or thread crest-to-crest diameter on the first, fourth, and last full threads (Fig . 1) . T. If the diameters 

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