Learn MoreBritish Standard Pipe Taper thread (BSPT) whose diameter increases or decreases along the length of the thread. BSPT thread is used where pressure-tightness is made through the mating of two threads together. International standards require all thread is parallel and male thread is tapered.
Learn MoreThe 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

Learn MoreNational Pipe Thread (NPT) is a family of technical standards for threads that has been adopted internationally for interconnecting hoses and fittings by mating an external (male) thread with an internal ( ) thread. National Pipe Threads are similar in function to BSP threads, but are not generally interchangeable.

ISO 228-1:2000 is the Code for parallel threads if that is what you are after, not standard BS 5200:1997. BS 5200:1997 is a specification for dimensions of hydraulic connectors and adaptors.

Learn MoreLikewise, pipe thread can be parallel (e.g., BSPP). For pipe thread, determine the size by comparing it with a nominal size profile, as shown in Figure 1 (a
Learn MoreTo find the thread size: 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 parallel male thread measures out to O.D 1″. Subtracting 1/4 gives a thread size of 3/4 also known as "dash" 12. Once you have the thread size, you then need to determine the.

Learn MoreAlthough BSP is a foreign thread, it isn't actually metric. This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. BSP parallel threads commonly seal via a 30° chamfer on the male thread to a 30° recessed. When the diameter smaller than 1/4", the value is indicated by a number, like #1 or No.1. 2.Thread sizes in metric are

Learn MoreBSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form). Here are the actual thread dimension data for BSPP and BSPT threads. The major diameter is a bit larger smaller than the actual OD of the pipe, and the minor diameter should be very close to what you would measure inside the
Learn MoreBSPP refers to parallel or straight threads. Meanwhile, BSPT refers to tapered threads. Sometimes BSPP threads are referred to as G threads and BSPT threads as R threads.
