Asc 310043609 Black Malleable Iron Reducing Tee 1-1/4x1x3/4

Product Description

The ASC ENGINEERED SOLUTIONS 310043609 is a black malleable iron reducing tee designed for threaded pipe assemblies in gas, air, and fluid distribution systems. The fitting connects a 1-1/4 inch run with a 1 inch outlet and a 3/4 inch branch, allowing a single fitting to step down flow in two directions simultaneously. Weighing 0.87 pounds, it is domestically manufactured and carries a black coating for corrosion resistance in exposed or semi-exposed installations. Licensed plumbers and pipefitters install this fitting in commercial and residential mechanical rooms, gas distribution headers, compressed air lines, and similar threaded iron pipe systems.

This reducing tee is suited for low-pressure gas piping, industrial air distribution, and general-purpose black iron pipe systems where a run reduction and a branch takeoff are needed at the same junction. The domestic origin supports project specifications that require USA-made fittings. It is appropriate for both new construction and retrofit work wherever NPT-threaded malleable iron fittings are called for.

Key Features

• Three-way reducing configuration: 1-1/4 inch run, 1 inch outlet, 3/4 inch branch
• Malleable iron construction for strength and impact resistance in threaded applications
• Black coating provides baseline corrosion protection for gas and air service
• Domestically manufactured to support USA-sourcing requirements
• Compact at 0.87 pounds, suitable for tight header or manifold assemblies

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT-threaded black iron pipe systems, including gas distribution and compressed air piping.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the pipe system fully before cutting into or threading any section. Apply listed thread sealant or PTFE tape rated for the intended service medium to all male NPT threads before assembly. Do not over-tighten; use a pipe wrench on the fitting body, not on the branch outlet, to avoid cracking the casting.
