National Pipe Thread (NPT)

National Pipe Thread (NPT) is a standardized screw thread system used mainly in plumbing and piping to connect pipes securely and prevent leaks. Its threads are tapered, meaning they gradually tighten as they are screwed together, creating a seal. NPT threads have specific dimensions and angles defined by industry standards, ensuring compatibility across different fittings and pipes. Their design allows for a tight, leak-proof connection suitable for transporting liquids and gases under pressure. In summary, NPT is a widely adopted threading method that ensures reliable and secure pipe connections in various industrial and household systems.
