In hydraulic systems, tapered threads play a crucial role due to their ability to self-seal directly along the thread flanks. However, because they all share a similar tapered profile that gradually narrows toward the tip, distinguishing between BSPT, NPT, and JIS Tapered threads with the naked eye is incredibly difficult. This article will guide you in selecting the correct thread
