1 inch x 3/4 inch Black Iron 90 Degree Reducing Elbow Female x Female

1" x 3/4" Black Malleable Iron 90° Reducing Elbow – For High-Integrity Threaded Connections

The 1" x 3/4" Black Malleable Iron 90° Reducing Elbow is engineered for joining pipes of different diameters at right angles in threaded piping systems. Manufactured to meet ANSI/ASME B16.3 specifications, this elbow supports dependable pressure handling in steam, gas, and water systems, making it suitable for commercial and residential service lines.

Advantages of Malleable Iron Construction

• ✅ High Tensile Strength – Withstands elevated pressures and mechanical stress in heating and gas systems.
• ✅ Corrosion Resistance – Black iron surface finish helps prevent external rust in dry installations.
• ✅ Thread Precision – Tapered NPT threads per ANSI B1.20.1 ensure secure, leak-tight seals with proper sealant.
• ✅ Dimensional Accuracy – Conforms to strict tolerance requirements, aiding alignment and flow performance.

Installation Notes

Installation of this reducing elbow requires properly prepared male NPT-threaded pipe ends and the application of an approved thread sealant or PTFE tape. Fittings should be tightened to manufacturer-recommended torque using appropriate tools to avoid over-stressing threads.

Specifications

• Material: Black malleable iron
• Size: 1" x 3/4" nominal pipe sizes
• Connection: Female NPT x Female NPT
• Angle: 90 degrees
• Standards: ANSI/ASME B16.3, UL and FM listed for specific services

Application Areas

This elbow is commonly utilized in gas and hydronic heating lines, fire protection loops, compressed air systems, and other general utility piping. Its reducing design allows for size transitions within confined layouts while maintaining directional control.

Note

Black malleable iron fittings are not intended for use in potable water systems due to material limitations related to corrosion and leaching standards. For potable applications, galvanized or brass alternatives should be considered.

The 1" x 3/4" Black Malleable Iron 90° Reducing Elbow provides a trusted solution for mechanical system routing and space-conscious installations. Its robust structure and certified performance make it a staple in professional-grade piping systems.
