Asc Engineered Solutions 311039408 Reducing Tee 3/4x1/4x3/4

Product Description

The ASC Engineered Solutions 311039408 is a galvanized malleable iron reducing tee designed for threaded pipe assemblies in plumbing, HVAC, and mechanical piping systems. Sized at 3/4 inch x 1/4 inch x 3/4 inch, this fitting accepts a reduced branch connection at the center port while maintaining full 3/4 inch flow on the run. The galvanized coating provides corrosion resistance for both indoor and outdoor installations. At 0.46 pounds, the fitting is domestic-manufactured and built to standard malleable iron fitting tolerances. Plumbers, pipefitters, and mechanical contractors install this type of fitting where a smaller branch takeoff is required from a main pipe run.

This reducing tee is suited for residential and light commercial threaded pipe systems, including gas distribution, water supply, and compressed air lines where branch reduction is needed. The 3/4 inch run ports connect to standard 3/4 inch NPT pipe, and the 1/4 inch branch port accommodates a smaller threaded connection such as a gauge tap, instrument port, or reduced-flow branch line. It is appropriate for use in exposed mechanical rooms, utility spaces, and behind-wall rough-in assemblies where a galvanized fitting is specified.

Key Features

• Malleable iron construction provides strength and resistance to impact and vibration in threaded piping systems
• Galvanized coating resists corrosion in both indoor and outdoor service environments
• Reducing branch port (1/4 inch) allows a smaller takeoff from a full 3/4 inch pipe run
• Domestic manufacture
• Lightweight at 0.46 pounds for easy handling during assembly

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 3/4 inch x 1/4 inch x 3/4 inch NPT threaded pipe systems using galvanized malleable iron fittings.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the IPC or IFGC. Shut off and depressurize the pipe system fully before cutting in or replacing any fitting. Apply approved thread sealant or PTFE tape to all male threads before assembly. Do not over-torque threaded connections, as malleable iron fittings can crack if excessive force is applied with power tools.
