NPT / PIPE

- National pipe tapered threads have been widely used for over 100 years. NPT is a U.S. standard for tapered threads used on pipes and fittings. They are used to effectively seal pipes for fluid and gas transfer. The nominal pipe size can be identified by physically measuring the thread diameter, then subtracting 1/4″.

- They are available in iron or brass for low-pressure applications and carbon steel and stainless steel for high-pressure.
