Asc Engineered Solutions 300059409 Cast Iron Steam Tee

Product Description

The ASC ENGINEERED SOLUTIONS 300059409 is a Class 125 black cast iron steam tee designed for steam distribution and low-pressure piping systems. This fitting connects three sections of pipe at a tee junction, with inlet and outlet dimensions of 3 inches by 2-1/2 inches by 3 inches. Cast iron construction provides the durability and heat tolerance required for steam service. Licensed plumbers and pipefitters install this fitting in commercial and residential steam heating systems where reliable, pressure-rated connections are required.

This tee is suited for low-pressure steam systems, including one-pipe and two-pipe steam heating configurations common in older residential buildings and light commercial applications. The black finish is standard for steam service fittings, distinguishing them from water service fittings. The Class 125 pressure rating aligns with typical low-pressure steam distribution requirements found in building heating systems.

Key Features

• Class 125 pressure rating for low-pressure steam service
• 3 inches x 2-1/2 inches x 3 inches configuration for reducing tee applications
• Cast iron construction rated for steam temperature and pressure demands
• Black finish standard for steam piping identification
• Three-way junction fitting for branching steam or condensate lines

Compatibility

Designed as an OEM-style replacement or new-installation fitting for Class 125 cast iron steam piping systems using standard NPT threaded connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical codes, including the International Mechanical Code and local steam piping regulations. Isolate and depressurize the steam system completely before removing or installing any fittings. Use appropriate pipe thread sealant rated for steam service when making threaded connections. Inspect mating pipe threads for damage before assembly to ensure a leak-free joint.
