Sigma 811007806 90 Deg Reducing Elbow 3/4x1/2 in 150 Lb

Product Description

The SIGMA 811007806 is a FIG 3101R 90-degree reducing pipe elbow rated at 150 lb, manufactured from galvanized malleable iron. It transitions from a 3/4-inch nominal female inlet to a 1/2-inch nominal female outlet using FNPT end connections on both ports. The galvanized finish provides corrosion resistance for use in exposed or moderately harsh environments. This fitting is used by licensed plumbers and pipefitters to change both flow direction and pipe size in a single component, reducing the need for an additional coupling in the run. It suits low-pressure water, steam, and air distribution systems within the 150 lb pressure class.

This reducing elbow is suited for residential and light commercial piping applications where a 90-degree directional change and a step-down in pipe size are required in the same fitting. Typical installations include water supply lines, compressed air distribution, and low-pressure steam systems. The FNPT threading allows straightforward installation with standard pipe thread sealant or PTFE tape. It is an import-grade fitting conforming to standard 150 lb malleable iron fitting dimensions.

Key Features

• 90-degree elbow with integral reducing capability eliminates the need for a separate reducing coupling
• 3/4 inch x 1/2 inch nominal FNPT connections on both ends
• 150 lb pressure class rating suitable for water, air, and low-pressure steam service
• Malleable iron construction provides strength and resistance to mechanical shock
• Galvanized finish adds corrosion protection for exposed or damp installations
• Standard FIG 3101R dimensional pattern for compatibility with common malleable iron fitting assortments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 150 lb malleable iron threaded piping systems using 3/4-inch to 1/2-inch nominal pipe size transitions.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and IFGC guidelines for threaded pipe connections. Shut off and depressurize the piping system completely before removing or installing any fitting. Apply an approved pipe thread sealant or PTFE tape to the male threads mating into this fitting before assembly. Do not over-tighten; use a pipe wrench with proper backup to avoid cracking the fitting body.
