Sigma 811010610 90 Deg Reducing Elbow 2x1 in Fnpt 150 Lb

Product Description

The SIGMA 811010610 is a 90-degree reducing pipe elbow rated at 150 lb, manufactured from galvanized malleable iron. It connects pipes of two different diameters while making a right-angle turn in the line, making it a common fitting in pressurized piping systems. The female NPT (FNPT) end style on both ports provides a threaded connection that seals reliably when properly taped and torqued. The 2-inch-by-1-inch nominal sizing makes this fitting suitable for transition points in distribution lines where flow is stepped down to a smaller branch. Licensed plumbers and pipefitters are the primary installers of this type of fitting.

This reducing elbow is used in residential and light commercial piping installations, including water supply, steam, and general-purpose threaded pipe systems rated at or below 150 lb working pressure. It is well suited for mechanical rooms, boiler rooms, and utility piping where directional changes and pipe-size reductions occur at the same point in the run. The galvanized finish provides corrosion resistance in exposed or moderately humid environments.

Key Features

• 90-degree turn with simultaneous 2-inch to 1-inch nominal pipe size reduction
• 150 lb pressure class malleable iron construction
• FNPT end style on both ports for standard threaded pipe connections
• Galvanized finish for corrosion resistance in exposed piping environments
• Suitable for water supply, steam, and general-purpose threaded pipe applications

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 150 lb malleable iron threaded pipe systems using 2-inch and 1-inch nominal FNPT pipe connections.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing codes and ASME B16.3 standards for malleable iron threaded fittings. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply thread sealant tape or compound to the male threads before engagement, and tighten to a firm, leak-free connection without over-torquing the fitting. Inspect all joints for leaks after restoring system pressure.
