Sigma 810039610 Malleable Iron Pipe Tee 1/2x1/2x3/4 in 150 Lb

Product Description

The SIGMA 810039610 is a reducing malleable iron pipe tee rated at 150 lb, designed for threaded pipe assemblies in plumbing, gas distribution, and general industrial piping systems. The tee features a 1/2 x 1/2 x 3/4 inch nominal configuration, with the 3/4 inch outlet on the branch run, making it suited for reducing branch connections where flow is directed from a larger header into a smaller run. The black oxide finish provides a base level of corrosion resistance for above-ground interior installations. This fitting is installed by licensed plumbers and pipefitters working on low-pressure threaded piping systems.

This tee is used in residential and light commercial applications where threaded malleable iron fittings are specified. Typical installations include natural gas supply lines, compressed air distribution, steam heating systems, and water service piping operating within 150 lb pressure class limits. The reducing branch outlet makes it a practical choice when transitioning between pipe sizes within a distribution network without adding an extra coupling.

Key Features

• 150 lb pressure class rating suitable for low-pressure threaded pipe systems
• Reducing configuration: 1/2 x 1/2 inch run with 3/4 inch branch outlet
• Malleable iron construction provides strength and thread integrity under torque
• Black oxide finish for corrosion resistance in dry, above-ground interior environments
• NPT-compatible threads for standard threaded pipe connections

Compatibility

Designed as an OEM-style replacement or standard-stock fitting for 150 lb rated threaded malleable iron piping systems using nominal 1/2 inch and 3/4 inch pipe.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, including the International Plumbing Code or International Fuel Gas Code as required by application. Shut off and depressurize the supply line completely before disassembly or fitting installation. Apply an approved pipe thread sealant or PTFE tape to male threads before assembly. Do not overtighten threaded connections, as malleable iron threads can crack under excessive torque.
