Sigma 810009209 90 Deg Reducing Elbow 1-1/4x3/4 in Fnpt 150lb

Product Description

The SIGMA 810009209 is a FIG 3101R 90-degree reducing pipe elbow rated at 150 lb, constructed from black oxide-coated malleable iron. It accepts a 1-1/4 inch nominal inlet and reduces to a 3/4 inch nominal outlet, with female NPT (FNPT) threading on both ends. This fitting is designed for threaded pipe assemblies in gas, water, and steam distribution systems operating within standard 150 lb class pressure limits. Licensed plumbers and pipefitters install this elbow when a directional change and simultaneous pipe reduction are required in a single fitting, eliminating the need for a separate reducing coupling.

This reducing elbow is suited for residential and light commercial piping installations where a 90-degree change of direction combined with a pipe size reduction from 1-1/4 inch to 3/4 inch is needed. Typical applications include branch takeoffs in heating system piping, domestic water supply lines, compressed air distribution, and low-pressure steam systems. The black oxide finish provides corrosion resistance appropriate for dry or mildly humid service environments.

Key Features

• 90-degree turn and pipe reduction combined in a single malleable iron body
• 1-1/4 inch x 3/4 inch nominal FNPT threaded ends for standard NPT pipe connections
• 150 lb pressure class rating suitable for water, gas, and low-pressure steam service
• Malleable iron construction provides impact resistance and ductility compared to cast iron
• Black oxide finish adds corrosion resistance for typical indoor piping environments

Compatibility

Designed as an OEM-style threaded fitting compatible with standard 150 lb class NPT malleable iron pipe fitting systems using 1-1/4 inch and 3/4 inch nominal threaded pipe.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local codes and the International Plumbing Code (IPC) or International Fuel Gas Code (IFGC) where applicable. Shut off and depressurize the pipe system completely before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before assembly, and tighten to the manufacturer-recommended engagement for the pipe size. Do not use this fitting beyond its rated 150 lb class pressure and temperature limits.
