FAQ:

Q: What is the difference between NPT and NPS thread?

A: Both NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys (this is a Sellers thread form).

Q: What is the use of NPT?

A: NPT threads are designed to be used with a sealing compound such as Teflon tape to create a leak-free seal , whereas NPTF threads form a mechanical seal by crushing the entire thread form. If NPT is used without a sealing compound then there can be leakages or other unpleasant issues.

Q: How do you measure NPT fittings?

A: How to measure NPT fittings. Align the 2.5 cm (1 inch) mark of a tape measure with one inside edge of the NPT fitting. Pull the tape measure across the opening of the fitting. Note the measurement to the other side of its other inside edge. Align and measure the distance across the narrowest part of the threads, if measuring a threaded NPT fitting.

Q: What is a NPT connection?

A: An NPT connection stands for National Pipe Thread, and the connection utilizes a male threaded adapter that connects with a female threaded adapter to create a seal.
