Sigma 810048819 Malleable Iron Reducing Tee 2x2x1.5in 150lb

Product Description

The SIGMA 810048819 is a standard reducing pipe tee manufactured from malleable iron with a black oxide finish. This fitting connects two run pipes at 2-inch nominal size and reduces the branch outlet to 1-1/2-inch nominal, allowing flow to be directed or divided across differently sized lines. All three ports use female National Pipe Taper (FNPT) thread ends for straightforward connection to standard threaded pipe. Rated at 150 lb, it is suited for low-pressure piping systems in commercial and industrial plumbing, steam distribution, gas distribution, and compressed air applications. Installation is performed by licensed plumbers or pipefitters working on threaded iron pipe systems.

This reducing tee is used in residential and commercial piping systems where a run line must branch off to a smaller-diameter service line. Common applications include steam and condensate lines, natural gas and propane distribution headers, fire protection headers, compressed air drops, and general industrial process piping. The 2-inch by 2-inch by 1-1/2-inch configuration is a frequently specified size in mechanical rooms and boiler rooms where a main line feeds a reduced branch for equipment connections or zone drops.

Key Features

• Reducing outlet allows a 1-1/2-inch branch from a 2-inch run without additional bushings
• Malleable iron construction provides strength and resistance to mechanical stress at threaded joints
• Black oxide finish offers baseline corrosion resistance for dry interior environments
• FNPT threads on all three ports are compatible with standard NPT pipe and fittings
• 150 lb pressure class suits low-pressure steam, gas, and compressed air service

Compatibility

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

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC). Shut off and depressurize the line completely before cutting into an existing system. Apply listed pipe thread sealant or PTFE tape to male threads before assembly, and tighten to proper engagement without over-torquing malleable iron threads. Inspect for leaks after restoring system pressure.
