Sigma 810023606 45 Degree Pipe Elbow 3/4 in 150 Lb Malleable Iron

Product Description

The SIGMA 810023606 is a 45-degree malleable iron pipe elbow rated at 150 lb, designed for threaded pipe systems in residential and commercial plumbing, HVAC piping, and mechanical installations. The black oxide finish provides a degree of corrosion resistance for dry or low-moisture environments. At 3/4 inch nominal pipe size, this fitting changes flow direction by 45 degrees and connects using standard NPT threads. Plumbers, pipefitters, and mechanical contractors install this type of fitting as part of gas, water, or steam distribution piping where a gradual directional change is required.

This elbow is suited for use in low-pressure threaded pipe assemblies operating within the 150 lb pressure class. Typical applications include residential gas piping, commercial hydronic systems, compressed air lines, and general-purpose water distribution. The malleable iron construction allows the fitting to withstand mechanical stress and vibration better than cast iron, making it a common choice in mechanical rooms and utility piping layouts.

Key Features

• 45-degree angle changes pipe direction with less flow restriction than a 90-degree elbow
• 150 lb pressure class rating for standard threaded pipe applications
• Malleable iron construction offers impact and vibration resistance
• Black oxide finish for surface protection in dry to low-moisture conditions
• 3/4 inch nominal pipe size with standard NPT threading

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with standard 3/4 inch NPT threaded pipe systems rated at 150 lb class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable codes such as the International Plumbing Code or International Fuel Gas Code. Shut off and depressurize the pipe system completely before cutting into any existing line. Apply an approved thread sealant or PTFE tape to all male NPT threads before assembly. Do not overtighten threaded connections, as malleable iron fittings can crack under excessive torque.
