Sigma 33RT1012006010C Malleable Iron Reducing Tee Fnpt 150 Lb

Product Description

The SIGMA 33RT1012006010C is a malleable iron reducing tee designed for threaded pipe systems in commercial and industrial piping applications. This black-finish fitting connects a 1-1/4 inch run to a 3/4 inch branch with a 1 inch outlet, using female national pipe taper (FNPT) threads on all three ports. Rated at 150 lb, it handles standard working pressures common in gas distribution, compressed air, and water piping systems. Malleable iron construction provides the ductility and impact resistance required for mechanical service environments where cast iron would be too brittle.

This reducing tee is suited for residential and light commercial gas piping, steam, air, and water distribution systems where a direction change and size reduction are needed at a single fitting. The FNPT threading makes it compatible with standard threaded pipe and fittings assembled using pipe dope or PTFE tape. It is typically installed by licensed plumbers, pipefitters, or gas technicians working on threaded black iron systems.

Key Features

• Malleable iron body provides ductility and resistance to mechanical shock
• 150 lb pressure rating suitable for gas, air, steam, and water service
• Three-port FNPT threading for standard tapered pipe thread connections
• Reducing configuration: 1-1/4 inch run x 3/4 inch branch x 1 inch outlet
• Black finish standard for gas and steam piping identification

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas technician in accordance with applicable IFGC, IPC, or local mechanical codes. Shut off all gas, water, or air supply and depressurize the line completely before disassembling or installing any threaded fitting. Apply pipe thread sealant or PTFE tape rated for the intended service medium to all male threads before assembly. Do not over-tighten; use a pipe wrench with a backup wrench to avoid stressing adjacent fittings or pipe.
