Swagelok® NPT pipe fittings provide reliable connections in pipe and tubing systems used in most industrial applications. They provide leak-tight performance while minimizing galling and optimizing the number of threads of engagement by exceeding the design requirements of industry standards.

Identify Thread Pitch and Size

These fittings are available in a range of shapes and materials, as well as a heavy-wall option in 316 stainless steel for applications up to 15 000 psig (1033 bar)—all manufactured to our exacting quality standards. Angles on elbows, tees, and crosses are rigidly controlled for accurate piping layout.
