2 inch Copper 45° Elbow – Wrought Copper Fitting for Directional Transitions

The 2 inch copper 45-degree elbow is a solder-joint fitting used to change flow direction in copper tube systems by 45 degrees. Manufactured from lead-free wrought copper, it complies with applicable codes for potable water, hydronic heating, and DWV systems. This fitting is commonly used in piping layouts where a gradual directional change is required to reduce turbulence and pressure loss.

Designed for compatibility with types L, M, and DWV copper tubing, the fitting features cup (socket) ends on both sides, enabling sweat connections using standard soldering practices. It meets requirements for pressure and non-pressure piping applications in residential, commercial, and institutional systems.

Technical Specifications

• Material: Lead-free wrought copper (≤0.25% lead content)
• Size: 2 inch nominal pipe size
• Angle: 45 degrees
• Connection Type: Cup x Cup (solder/sweat)
• Standards: Meets ASME B16.22 and NSF/ANSI 61 & 372

Performance Characteristics

• ✅ Lead-Free Compliance: Certified for potable water systems in accordance with national lead reduction mandates
• ✅ Smooth Flow Transition: Provides a more gradual directional change than 90° elbows, reducing velocity-related issues
• ✅ Thermal Stability: Suitable for hot and cold water systems, including hydronic loops
• ✅ Corrosion Resistant: Copper alloy resists pitting and internal buildup in water-bearing systems

Installation Considerations

Ensure all mating surfaces are cleaned and fluxed prior to soldering. Apply even heat to achieve full capillary fill. Use ASTM B88-compliant tubing for compatible sizing. For systems requiring inspection or code approval, installation must meet IPC/UPC guidelines and local code amendments.

Typical Applications

This fitting is used in:

• Potable water supply lines
• Hot water recirculation loops
• Hydronic heating systems
• DWV configurations requiring gradual direction changes

Regulatory Note

All copper fittings installed in potable water systems must meet low-lead requirements per the Reduction of Lead in Drinking Water Act. This 2 inch copper 45° elbow meets NSF/ANSI 61 and NSF/ANSI 372 certifications and is approved for use in all 50 states.

The 2 inch copper 45-degree elbow is a durable, code-compliant solution for directional flow changes in plumbing and mechanical piping systems. Its consistent dimensions, lead-free alloy, and field-proven reliability make it a standard fitting in professional-grade installations.
