3/4 inch Copper 45° Elbow – Wrought Copper Fitting for Directional Transitions

The 3/4 inch Copper 45-Degree Elbow is a solder joint fitting designed to redirect flow at a 45° angle in copper tube systems. Manufactured from wrought copper conforming to ASTM B75 Alloy C12200, this elbow is suitable for use in potable water, HVAC, and hydronic heating applications requiring smooth directional changes while maintaining flow efficiency and pressure integrity.

This fitting is designed for use with soldered copper tube connections and complies with ASME B16.22 dimensional standards. Its long-radius arc reduces turbulence and helps maintain velocity through the system, making it a standard component in both residential and commercial mechanical layouts.

Product Specifications

• ✅ Nominal Size: 3/4 inch
• ✅ Type: 45° elbow – long radius
• ✅ Material: Wrought copper (ASTM B75, Alloy C12200)
• ✅ Connection Type: Cup (sweat) x Cup – solder joint
• ✅ Compliance: ASME B16.22, NSF/ANSI 61 and NSF/ANSI 372 (lead-free)

Performance Characteristics

• ✅ Corrosion Resistance Copper alloy construction resists scale and deterioration in potable water systems.
• ✅ Thermal Stability Maintains mechanical integrity under elevated temperatures, making it suitable for hot water supply and heating systems.
• ✅ Low-Turbulence Flow 45° arc allows for smoother directional changes compared to 90° fittings, minimizing friction loss.
• ✅ Code-Compliant Design Engineered for consistent performance in code-regulated applications across residential and commercial systems.

Installation Considerations

Prepare copper tube ends by cutting square, deburring, and cleaning prior to applying lead-free solder and flux. Ensure proper dry fit before heating. For critical applications, follow IPC/UPC or project-specific specifications regarding fitting spacing, flame control, and pressure testing.

Common Applications

This 3/4 inch copper 45° elbow is typically used in domestic water lines, mechanical room piping, hot water circulation loops, and vent branches. It is favored where space constraints or fluid dynamics require a gradual directional change rather than a sharp 90° turn.

Technical Note

Compared to 90-degree elbows, 45-degree fittings are commonly selected to improve system flow characteristics and reduce stress on pump-driven loops or gravitational drainage paths.

The 3/4 inch Copper 45° Elbow is an essential component for directional routing in copper tube systems, offering performance, durability, and compliance with modern mechanical specifications.
