Sigma 811008606 90 Deg Reducing Elbow 1x1/2 in Fnpt 150lb

Product Description

The SIGMA 811008606 is a FIG 3101R 90-degree reducing pipe elbow rated at 150 lb, constructed from galvanized malleable iron. It accepts a 1-inch nominal pipe on the run end and reduces to a 1/2-inch nominal pipe on the outlet end, with female National Pipe Taper (FNPT) threads on both ends. This fitting is designed for use in threaded pipe assemblies where a directional change and size reduction are needed in a single fitting. Plumbers and pipefitters install this type of fitting in gas, water, and general-purpose piping systems where a 90-degree turn and a pipe size transition occur at the same point.

This reducing elbow is suited for residential and light commercial plumbing and mechanical piping installations. It is commonly used in branch connections, supply drops, and equipment hookups where space constraints make a combined elbow-and-reducer fitting practical. The galvanized finish provides corrosion resistance for exposed or damp-location installations. Threaded assembly follows standard NPT practices and is compatible with Schedule 40 threaded pipe.

Key Features

• 90-degree turn with integral pipe size reduction — eliminates need for a separate coupling and elbow
• 150 lb pressure-rated malleable iron construction for durability in demanding piping systems
• FNPT threads on both ends for standard NPT threaded pipe compatibility
• Galvanized finish for corrosion resistance in damp or exposed installations
• 1-inch x 1/2-inch nominal sizing for common branch and drop piping transitions

Compatibility

Designed as an OEM-style threaded pipe fitting compatible with Schedule 40 NPT-threaded pipe systems in standard 150 lb malleable iron piping assemblies.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC or IFGC requirements for the service type. Apply appropriate thread sealant or PTFE tape to all male threads before assembly. Shut off supply pressure and depressurize the line before disassembling or modifying any threaded connection. Do not overtighten FNPT fittings — hand-tight plus two to three turns with a pipe wrench is the standard practice for malleable iron threaded fittings.
