Value Brand 3/8 in Malleable Iron Tee Class 300

3/8 in Class 300 Malleable Iron Tee

This malleable iron tee provides a three-way FNPT connection for piping systems rated to Class 300. It meets ASME B 16.3 and B 16.4 standards and carries FM Approved and UL Listed marks. The fitting suits installers needing a durable branch connection in high-pressure service.

Capacity and headroom

The tee handles a maximum pressure of 2000 psi at 150 degrees F and saturated steam pressure of 300 psi. Its temperature range extends from -20 degrees to 550 degrees F, covering most industrial steam and hydraulic lines. It is not suited for services exceeding these pressure or temperature limits.

Upgrade path

This fitting replaces lower-class tees that cannot meet Class 300 pressure requirements or the listed safety certifications. The jump is worth it when system design demands ASME B 16.3 compliance and a 2000 psi rating at 150 degrees F. It does not address needs for larger pipe sizes or different connection types.
