Sigma 810038810 Malleable Iron Pipe Tee 3/4x1/2x1/2 in 150 Lb

Product Description

The SIGMA 810038810 is a reducing malleable iron pipe tee with a black oxide finish, rated at 150 lb, and threaded with female NPT (FNPT) connections on all three outlets. It transitions from a 3/4-inch run to two 1/2-inch branch connections, making it a standard reducing tee for low-pressure piping systems. The malleable iron construction provides the ductility and impact resistance needed for threaded pipe assemblies in gas, air, and water service applications. Licensed plumbers, pipefitters, and HVAC techs regularly specify this fitting class for residential and light commercial installations.

This fitting is suited for use in residential and light commercial piping systems where a run reduction or branch split is required. Typical applications include natural gas distribution lines, compressed air systems, and water supply piping where 150 lb Class malleable iron fittings meet system pressure and code requirements. The black oxide finish provides a standard appearance and minimal surface protection consistent with typical black iron gas piping installations.

Key Features

• Reducing tee configuration: 3/4 x 1/2 x 1/2 inches nominal
• 150 lb pressure class malleable iron construction
• Female NPT (FNPT) threads on all three connections
• Black oxide finish standard for black iron gas piping systems
• Malleable iron provides ductility and resistance to cracking under stress

Compatibility

Designed as a standard 150 lb Class malleable iron reducing tee compatible with FNPT-threaded pipe systems requiring a 3/4 x 1/2 x 1/2 inch nominal reducing configuration.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable codes such as the IFGC or IPC. Shut off and depressurize the system completely before cutting into any existing piping. Apply appropriate thread sealant or PTFE tape rated for the intended service medium before threading the fitting onto pipe. Do not over-torque the fitting, as malleable iron threads can crack under excessive force.
