NPT stands for National Pipe Thread, a U.S. standard for tapered threads used on pipes and fittings, including those made of PVC (polyvinyl chloride). These threads are designed to create a tight, leak-proof seal when joining pipes or fittings together. NPT threads have a taper to them, which means that the diameter of the thread gets smaller as you move further from the end of the fitting. This tapering helps create a tighter connection as the fitting is screwed into place.

Key Features of NPT Threads:

  • Tapered Design: The taper helps ensure that when you tighten the fitting, the threads bind together to form a leak-proof seal.
  • Standard Sizes: NPT threads come in standard sizes, making it easier to find compatible parts.
  • Sealing Method: NPT fittings often require a thread sealant, such as Teflon tape or pipe dope, to prevent leaks.

Application in PVC Fittings:

NPT threads are commonly used in both Schedule 40 and Schedule 80 PVC fittings for applications in plumbing, irrigation, and other fluid-handling systems. The threads provide a strong mechanical connection, making them suitable for pressurized systems where leak prevention is crucial.

Understanding NPT is important for choosing the right fittings for your project, ensuring compatibility, and achieving a secure and durable seal.
