Asc Engineered Solutions 311044200 Reducing Tee 1-1/4x3/4x1 in

Product Description

The ASC ENGINEERED SOLUTIONS 311044200 is a galvanized malleable iron reducing tee designed for threaded pipe assemblies in plumbing, HVAC, and mechanical piping systems. This fitting connects a 1-1/4 inch run to a 3/4 inch branch outlet with a 1 inch inlet on the opposite run end, allowing flow to be redirected or split across different pipe sizes within the same system. The galvanized coating provides corrosion resistance suited to wet or exposed service environments. At 0.88 pounds, the malleable iron construction offers the durability and ductility required for pressurized service lines where rigid cast iron would be too brittle.

This reducing tee is used in residential and commercial piping installations where threaded iron pipe is the standard — including domestic water supply, gas distribution, steam, and compressed air lines. It is well suited for mechanical rooms, boiler rooms, and utility piping where mixed pipe diameters must be joined at a tee junction. Domestically manufactured, it meets expectations for dimensional consistency in standard NPT threaded systems.

Key Features

• Reducing configuration: 1-1/4 inches x 3/4 inches x 1 inch for multi-diameter pipe runs
• Galvanized coating for corrosion resistance in wet or exposed environments
• Malleable iron construction provides ductility and strength under pressure
• Threaded ends compatible with standard NPT pipe threads
• Domestically manufactured for dimensional consistency

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT threaded iron pipe systems with a 1-1/4 inch run, 3/4 inch branch, and 1 inch inlet configuration.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters working under applicable IPC or IFGC code requirements. Shut off and depressurize the line completely before removing or installing any threaded fitting. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly, and tighten to hand-tight plus the appropriate number of turns using a pipe wrench — do not overtighten malleable iron fittings as the material can crack under excessive force. Verify system pressure rating compatibility before returning the line to service.
