PIPE / PIPE THREAD DIMENSIONS Nominal Pipe sizes do not match any of its actual physical dimensions. The outside diameter of each pipe fitting must be measured and compared to the table for size identi-fication. The thread on the BSPP just forces the seal on the mating shoulder. Of these, the most significant is geographical location. In addition, we’ll cover some of the most common port thread types including NPT/NPTF, BSPP (also known as G), BSPT, PT, Metric (M) and SAE. * BSPT -British Standard Pipe Taper * BSPP -British Standard Pipe Parallel Visit the post for more. thread dimension Chart FEMALE ThrEAd MALE ThrEAd M16/ 5 / 8 ” ET M20/ 3 / 4 ” ET M25/1” ET M32/1 1 / 4 ” ET M40/1 1 2 ” ET M50/2” ET M63/2 1 2 ” ET M75/3” ET 1 / 2 ” N pT/BSp 3 4 ” N 1” N pT/BSp 1 1 / 4 ” N pT/BSp / 2 pT/BSp 2” N pT/BSp 2 / 2 ” N pT/BSp 3” N pT/BSp 3 / 2 pT 4” N pT ThrEAdS pEr INCh pITCh BOrE American National Pipe – NPT/NPS American National pipe ( NPT , NPS), Like British Standard Pipe ( BSP ), is designated by trade size, rather than actual diameter, as shown in the table below. Both NPT and BSP are pipe thread standards for screw threads used on pipes and pipe fittings to seal pipes. . History of Pipe Threading and Standards. For pipe thread, determine the size Thread angle is different (55° vs 60°). BSPT Connections. NPT threads have a 60° included angle and have flattened peaks and valleys (this is a Sellers thread form); BSP threads have a 55° included angle and have rounded peaks and valleys (this is a Whitworth thread form). What is the types of pipe threads that exist? National Pipe Thread - NPT, British Standard Pipe - BSP, and so on. Example: 1/8 NPT thread = 1/8 NPT We have compiled a simple step-by-step guide to help you identify your thread type. Instrumentation Pipe Fittings. And here is a link to the pipe thread acronyms. An Adaptor NPT x BSPT is a Threaded Pipe fitting which consists of a short piece of Hex pipe, provided with a NPT female pipe thread at one end and a BSPT male pipe thread at another, for connecting two other fittings. Always remember that NPT threads have a 60° thread flank angle, and BSPT has a 55° angle (this can be verified with a thread gauge). The BSPT on the other hand is the most commonly used thread in other countries. * BSPT -British Standard Pipe Taper * BSPP -British Standard Pipe Parallel National Pipe Thread Basic Dimensons, American Standard Taper Pipe Threads, NPT. ISO Parallel threads are equivalent to DIN ISO 228/1, BSP PL, JIS B0202, G 1/8 and G 1/4 etc. Thread angle is different (55° vs 60°).

You’ll need a couple tools on hand to make the process easier, but a straight steel ruler may work as well
