The most common types of Whitworth thread are: BSPP (G) – British Standard Pipe Parallel. BSPT (R/Rp) – British Standard Tapered Pipe, for pipes and tapered thread. An appropriate sealing compound can be used in the thread to ensure a leakproof joint. If you have any questions please contact us or check out our fittings with BSPP/ BSPT (G

Using the table below we can see that a thread measuring 1/2" is actually a 1/4" BSP thread. Similarly, a thread that measures 1" is actually a 3/4" BSP 

You can cross-reference the bore size on the following chart with thread pitch and threads per inch to find your desired size and its related specs. BSPT-tech.

The main difference between NPT and BSP threads is that the thread angle in NPT threads is 60 degrees while that of BSP pipes is 55 degrees. NPT threads are also pointed at the crests and

1) Measure the O.D (Outer diameter) of the BSP thread. 2) Take the O.D measurement in inches and subtract 1/4 (.25″). For example, a BSP

The British standard pipe thread (BSP thread) is a family of standard screw thread types that has been adopted internationally for interconnecting and sealing pipe ends by mating an external (male) with an internal ( ) thread. Types Two types of threads are distinguished: • Parallel threads, which have a constant diameter.(G)

British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external thread with an internal ( ) thread.It has been adopted as standard in plum and pipe fitting, except in North America, where NPT and related threads are used.

04/10/  · The second kind of BSP thread is the taper thread. The British Standard Pipe Taper thread (BSPT) has a changing diameter. It may increase or decrease along the length of the thread. Some taper threads have the letter R on them as an identifier. It's common to incorrectly identify tapered pipes as NPT pipes. However, NPT pipes have a 60° flank

NPTF, BSPT and BSPP measure 1/4" larger than their actual size. For example, a 1/4" NPTF, BSPT or BSPP will actually measure 1/2" on the O. D. of the threads. JIC, SAE O-ring & Flat Face threads measure as listed below. The first number listed is the size of thread, the second number is the threads per inch. Adapter Sizing Chart Thread

BSP Thread Type - British Standard Pipe This is a standard thread type that has been adopted internationally for interconnecting and sealing pipe ends. You'll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. BSPP refers to parallel or straight threads. Meanwhile, BSPT refers to tapered threads.

NPT fittings will have threads with a 60 degree spread while BSP threads will have a 55 degree spread. A manual thread pitch gauge. Use this chart to easily compare NPT and BSP. How to Measure Threads Whether you're working with NPT or BSP fittings, you'll typically be able to tell the difference between tapered and straight connections.
