1-1/4 inch Galvanized Iron 90 Degree Street Elbow Female x Male

1-1/4 inch Galvanized Iron 90° Street Elbow – Threaded Fitting for Directional Transitions

The 1-1/4 inch Galvanized Iron 90-Degree Street Elbow is designed for directional changes in threaded piping systems. Featuring one male and one female NPT threaded end, this fitting enables direct connection to female fittings without the need for an additional nipple, reducing space and material requirements.

Constructed from galvanized malleable iron, this elbow is hot-dip zinc coated to resist corrosion and is intended for use in low-pressure piping systems that carry water, air, oil, or non-aggressive fluids. It is suitable for both residential and commercial installations where threaded pipework is employed.

Performance Characteristics

• Connection Type: Male NPT x Female NPT
• Angle: 90 degrees for tight directional transitions
• Material: Galvanized malleable iron per ASTM A197/A197M
• Finish: Zinc-coated via hot-dip galvanizing to ASTM A153
• Pressure Rating: Suitable for maximum 150 PSI non-shock working pressure (varies by application)

Compliance & Standards

• Conforms to ANSI/ASME B16.3 for malleable iron threaded fittings
• Zinc coating complies with ASTM A153, providing enhanced corrosion resistance
• Threading complies with ANSI B1.20.1 for tapered pipe threads

Installation Considerations

To install, ensure all threads are clean and free of debris. Apply appropriate pipe joint compound or PTFE thread sealant tape to male threads. Thread the fitting hand-tight and then tighten further with a wrench, taking care not to overtighten and compromise the seal or damage the fitting. Avoid using in systems where exposure to corrosive or acidic substances is expected, as zinc may degrade under such conditions.

Application Scope

Used primarily in water distribution, low-pressure air, fire protection (dry systems), and process piping. Commonly found in system branches, boiler rooms, HVAC lines, and mechanical rooms. The street elbow design simplifies assembly in tight configurations by eliminating the need for a short nipple between fittings.

Note on Galvanized Iron Fittings

Galvanized iron offers moderate corrosion resistance in typical indoor and dry outdoor environments. Not recommended for potable water systems in certain jurisdictions due to concerns about zinc leaching over time. Always confirm with local plumbing codes before use in domestic water supply lines.

The 1-1/4 inch Galvanized Iron 90° Street Elbow provides a compact and reliable method for directional changes in threaded pipe systems, supporting consistent performance under appropriate conditions. Proper selection and installation of this fitting contribute to the long-term reliability of mechanical and plumbing networks.
