Sigma 810049809 Malleable Iron Pipe Tee 2x1-1/2x2 in 150 Lb

Product Description

The SIGMA 810049809 is a malleable iron pipe tee rated at 150 lb, designed for joining threaded pipe runs in low-pressure plumbing, gas distribution, and general mechanical piping systems. The reducing tee connects a 2-inch run with a 1-1/2-inch branch outlet, allowing directional splits or takeoffs in a threaded black iron piping layout. The black oxide finish provides a standard surface treatment appropriate for exposed or concealed interior installations. Licensed plumbers and pipefitters are the primary installers for this fitting in both residential and light commercial settings.

This tee is suited for threaded black iron pipe systems used in natural gas, propane, steam, and water service applications rated within the 150 lb pressure class. The reducing configuration makes it a common choice in branch-line takeoffs where a main 2-inch run feeds a 1-1/2-inch secondary line. Typical installation scenarios include boiler rooms, mechanical rooms, and gas distribution manifolds where standard NPT threaded fittings are required.

Key Features

• Malleable iron construction provides strength and impact resistance in threaded piping systems
• 150 lb pressure class rating for low-pressure gas, steam, and water service
• Reducing tee configuration: 2-inch run by 1-1/2-inch branch outlet
• Black oxide finish suitable for standard interior mechanical installations
• NPT threaded connections on all three ports for compatibility with standard black iron pipe

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard 150 lb threaded malleable iron pipe systems using NPT connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an appropriate thread sealant or PTFE tape to all male NPT threads prior to assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
