Product Drawing
American standard Thread
The standard is ANSI/ASTM B1.20.1 and include tapered and parallel teeth for a variety of uses including rigid, pressure sealing or both. The thread angle (the angle between the thread side and the vertical plane of the bolt axis) is 60 degrees. The peak/trough of the spiral (the most protruding top of the thread is called the spiral peak, and the most concave point of the thread is called the spiral valley) presents an acute angle. There are abbreviations for various subdivision types due to their uses. The common NPT is the abbreviation of American tapered teeth, and the American parallel teeth are abbreviated as NPS. Mainly used in North America.
What is NPT or NPS
NPT: National pipe thread, full name: American National Standard Taper Pipe Thread. It is an American tapered thread standard commonly used in general industrial components. It is often used for sealing industrial components that cannot or do not require any seals, and have a wide range of applications. It can be used in external threaded and internal threaded.
NPS: National pipe straight, full name: American National Standard Straight Pipe Thread. It is an American parallel thread standard commonly used in general industrial components. For rigidity requirements, seals need to be used; It can only be internal threaded.
