If you’ve worked with plumbing systems, you’ve likely encountered the term NPT (National Pipe Tapered) thread. But what does NPT mean in plumbing, and why is it so important? Understanding how NPT works—and how it differs from other pipe threads for plumbing—can prevent costly mistakes, leaks, and connection failures.

In high-pressure industrial systems, the smallest component can make the biggest difference. Pipe threads are a prime example. These helical grooves, which allow pipes and fittings to connect securely, are essential for sealing systems that transport fluids or gases under pressure. Selecting the right pipe thread size ensures leakproof connections, consistent flow, and long-term durability.
