1-1/2" FNPT Galvanized Tee

This galvanized malleable iron tee provides a threaded branch connection for 1-1/2 inch nominal pipe. It is rated Class 300 and meets ASME B16.3 and B16.4 standards for dimensional compliance. The fitting carries FM approval and UL listing for fire protection and safety applications. Suitable for water, oil, and gas piping systems up to the rated pressures.

Installers needing a Class 300 threaded branch

Plumbers and pipefitters working on high-pressure water, oil, or gas lines will find this fitting appropriate for the specified service conditions. It is not intended for systems requiring welded or flanged connections, nor for applications exceeding the 1500 psi WOG rating. Buyers needing a different pipe size, connection type, or material grade should select an alternative fitting.

Handles 1500 psi WOG and 300 psi saturated steam

The tee comfortably manages non-shock cold working pressures up to 1500 psi at 150 degrees Fahrenheit. It also supports saturated steam service up to 300 psi within the same temperature limit. Headroom diminishes for services above these pressures or for temperatures exceeding the rated maximum. Always verify system design pressure against the fitting class.
