Sigma 33RT1012006012C Malleable Iron Reducing Tee 150 Lb

Product Description

The SIGMA 33RT1012006012C is a black malleable iron reducing tee rated for 150 lb service. It features a 1-1/4 x 3/4 x 1-1/4 inch nominal configuration with female NPT (FNPT) end connections on all three ports. The reducing outlet at the branch allows a smaller-diameter line to tap off a main run without additional bushings in many installations. Licensed plumbers and pipefitters install this fitting in low-pressure gas, air, steam, and water distribution systems where a durable threaded iron fitting is specified.

This reducing tee is suited for residential and light commercial piping applications including natural gas distribution, compressed air lines, and hot or cold water systems where malleable iron fittings meet the design spec. The FNPT thread pattern conforms to ANSI/ASME B1.20.1 standards, making it compatible with standard NPT-threaded pipe, valves, and equipment across a wide range of trade installations.

Key Features

• Reducing tee configuration: 1-1/4 x 3/4 x 1-1/4 inch nominal, reducing branch port
• 150 lb pressure rating suitable for low-pressure gas, steam, air, and water service
• Female NPT (FNPT) connections on all ports for standard threaded pipe assembly
• Malleable iron construction provides impact resistance and machinability compared to cast iron
• Black finish standard for gas and air service piping

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard NPT-threaded malleable iron piping systems rated at 150 lb class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes, IFGC, or IPC requirements. Shut off and depressurize the line completely before disassembling or threading fittings. Apply an appropriate thread sealant or PTFE tape to male threads before assembly. Do not over-torque threaded connections, as malleable iron fittings can crack if excessive force is applied.
