Sigma 33RT1012010004C Reducing Tee 1-1/4x1x1/2 in Fnpt 150lb

Product Description

The SIGMA 33RT1012010004C is a black malleable iron reducing tee designed for low-pressure piping systems in gas, steam, and water distribution applications. With a nominal size of 1-1/4 x 1 x 1/2 inches and a 150 lb pressure rating, this fitting accepts female NPT (FNPT) connections on all three ports. The reduced outlets allow branch connections at different pipe diameters without additional bushings in many configurations. Malleable iron construction provides the ductility needed to handle mechanical stress and vibration common in mechanical room and rough-in installations. Licensed plumbers, pipefitters, and gas mechanics are the typical installers.

This reducing tee is suited for residential and light commercial piping installations where a main run must be reduced or branched at a smaller diameter. Common applications include natural gas distribution, steam and condensate piping, and potable or non-potable water systems that use threaded black iron pipe. The FNPT end style makes it compatible with standard NPT-threaded pipe and fittings throughout the run.

Key Features

• Nominal size: 1-1/4 inches (run) x 1 inch (run) x 1/2 inch (branch)
• 150 lb pressure-class rating for low-pressure gas, steam, and water service
• Female NPT (FNPT) threads on all three ports for standard threaded connections
• Malleable iron construction offers ductility and resistance to mechanical shock
• Black finish suitable for gas piping and non-corrosive indoor applications
• Reducing configuration eliminates the need for separate bushings in many branch scenarios

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or gas mechanic in accordance with applicable local codes, the International Fuel Gas Code (IFGC), or the International Plumbing Code (IPC) as required by the service type. Shut off and depressurize the piping system completely before disassembling or installing any threaded fittings. Apply an approved thread sealant or PTFE tape to male threads before assembly — do not apply sealant to female threads. Hand-tighten first, then use a pipe wrench to achieve a secure, leak-free joint without over-stressing the fitting.
