External Pipe Threads per. ISO 228-1, Pipe threads where pressure-tight joints are not made by the threads. These pipe threads are also known as Whitworth pipe threads. Where: D = Major Dia.internal thread D 1 = Minor Dia.internal thread D 2 = Pitch diameter internal thread d = Major Dia.external thread d 1 = Minor Dia.external thread

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.

NOTE: It is a common mistake to identify a BSPT (tapered) as an NPT. Remember that NPT threads have a 60° thread flank angle, and BSPT has a 55° angle (this can be verified with a thread gauge). Although BSP is a foreign thread, it isn't metric. This is why it comes in imperial sizes: 1/8, 1/4, 1/2, 3/4, and so on. Thread conforms to ISO 228-1.

BSP threads are identified with letters each of which represents the type of thread and their associated standards 1:.

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 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 Thread Type - British Standard Pipe You'll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. Find the caliper measurement in the chart and cross reference the nominal NPT pipe size. Don't get confused, the actual measurement is not the same as the NPT pipe size. Is SAE and UNF the same?

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
