systems. The BSP thread is offered in a straight (parallel) form known as BSPP and a tapered form known as BSPT. These threads feature a 55° flank angle. Fittings in this section with male BSPP threads use a primary sealing method of an O-ring and retaining ring, as shown in Fig. G5. Fig. G5 — O-Ring with Retaining Ring

National 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.

BSP 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

Likewise, 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 

To 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.

of BSPP adapters, most all males in series "B" can be used for as a Port Connection with the addition of a bonded seal. Measurement Procedure 1. With calipers, measure the O.D. (outer diameter) of the Male threads or the I.D. (inner diameter) of the threads. 2. Check the thread pitch with the thread pitch gauges. 3.

BSPP 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. Are you confused yet? Note: JIS tapered pipe thread (PT thread) is interchangeable with BSPT thread. *O.D. = Outside Diameter I.D. = Inside Diameter Go to top

27/08/  · If pipe threads were proprietary information like the Microsoft products, they would most likely sell for $100 per threaded connection. 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.

If the diameter stays the same from the first to last thread then the thread is classified as a parallel thread (BSPP). Once it is known whether the thread is 

British Standard Pipe fittings are among the most popular of all foreign threads in the world today. These threads come in two versions: parallel (BSPP), 

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

BSP: Represents British standard thread, also known as Wyeth profile angle 55 °. BSPT stands for British standard taper pipe thread profile according to AS 1722.1, BS 21, ISO 7. BSPP: Represents British standard straight pipe thread profile according to AS 1722.2, ISO 228. BSPT external thread and BSPT non-adjustable internal thread seal.

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. BSP threads are usually straight/parallel while NPT threads are usually tapered. If the threads are the same size then it is BSP whereas if the first thread is small (in diameter) that the last then it
