🔍 Key Concepts

• Pipe thread designations such as 1/8-27 NPT and what each part (1/8, 27, NPT) refers to • Difference between thread profile (shape of the thread) and thread series/standard (system or family of threads) • Meaning of engineering terms class of fit and class of finish in threaded connections

💭 Think About

• Look at other common designations like 1/2-13 UNC or 3/8-16 UNF. What do the letters at the end (UNC, UNF, NPT) usually describe? • In a pipe fitting catalog, when you see NPT, BSP, or metric threads listed, are they talking about the shape of a single thread or the overall standard/system that thread follows? • Which answer choice best matches the idea of a named standard for pipe threads used in fluid systems?

✅ Before You Answer

• Be clear on what 1/8 and 27 already tell you (size and threads per inch), so you don’t duplicate that meaning with your choice. • Eliminate any options that refer to surface quality or tight/loose tolerance rather than the naming of a thread standard. • Choose the option that matches a named thread system/family used across many fittings, not a detail of one specific machined surface.
