Sigma 811024009 45 Deg Pipe Elbow 1-1/4 in Fnpt 150 Lb

Product Description

The SIGMA 811024009 is a 45-degree malleable iron pipe elbow rated at 150 lb for use in threaded piping systems. It features a 1-1/4 inch nominal size with female NPT (FNPT) end connections on both ends, making it suitable for standard threaded pipe installations. The galvanized finish provides corrosion resistance for applications in moist or moderately corrosive environments. This fitting is installed by licensed plumbers and pipefitters working on gas, water, or general-service piping systems that require a 45-degree direction change.

This elbow is suited for residential and light commercial piping applications where a 45-degree change of direction is needed in a 1-1/4 inch threaded line. Common install scenarios include supply water lines, low-pressure gas distribution piping, and HVAC condensate or auxiliary piping. The 150 lb pressure class makes it appropriate for standard-service, non-high-pressure threaded systems. The galvanized coating adds service life in installations exposed to moisture or outdoor conditions.

Key Features

• 45-degree elbow provides direction change in threaded piping runs
• 1-1/4 inch nominal FNPT connections on both ends for standard threaded pipe
• 150 lb pressure class rating suitable for standard-service applications
• Malleable iron construction provides strength and impact resistance
• Galvanized finish for corrosion protection in moisture-prone environments

Compatibility

Designed as an OEM-style replacement fitting compatible with standard 1-1/4 inch NPT threaded pipe systems rated at 150 lb service class.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable local plumbing and mechanical codes. Shut off and depressurize the piping system completely before removing or installing any fittings. Apply thread sealant or PTFE tape to all male threads per standard practice before making up the joint. Do not over-tighten threaded connections, as malleable iron fittings can crack if excessively stressed.
