1-1/2 inch Copper 45 Degree Elbow Copper x Copper

1-1/2” Copper 45° Elbow – Wrought Copper Fitting for Directional Change

The 1-1/2” copper 45-degree elbow is a solder-joint fitting used to alter the direction of copper tubing in water distribution or mechanical piping systems. Manufactured from lead-free wrought copper, this elbow complies with ASTM and NSF standards for potable water and is commonly installed in pressure and non-pressure lines requiring a gradual directional transition.

This fitting features a 45-degree bend with female sweat (cup) connections on both ends, making it compatible with type L, M, and DWV copper tubing. Its short radius design facilitates compact installations where space is limited, while maintaining proper flow dynamics and minimizing head loss in the system.

Technical Specifications

• Material: Lead-free wrought copper (≤0.25% lead content)
• Size: 1-1/2 inch nominal tubing diameter
• Connection Type: Cup x Cup (solder joint)
• Angle: 45 degrees
• Standards: ASTM B75/B88, ANSI/NSF 61 and 372 compliant

Key Features

• ✅ Gradual Directional Change Ideal for systems requiring smoother transitions than a 90° fitting
• ✅ Lead-Free Compliance Suitable for potable water applications under U.S. Safe Drinking Water Act requirements
• ✅ High-Temperature Tolerance Suitable for hot and cold water, hydronic heating, and closed-loop systems
• ✅ Pressure Rating: Up to 200 PSI at 200°F when properly installed
• ✅ Uniform Wall Thickness Provides consistent heat transfer during soldering and long-term mechanical stability

Installation Considerations

This fitting is intended for sweat (soldered) installation. Ensure all tubing ends and fitting sockets are cleaned and fluxed prior to assembly. Apply even heat with an appropriate torch, allowing solder to fill the joint fully per standard plumbing practice. Always verify that installation complies with applicable local and national codes (e.g., IPC, UPC).

Typical Applications

The 1-1/2” copper 45-degree elbow is used in:

• Potable water supply lines (residential and commercial)
• Chilled and hot water loops in HVAC systems
• Non-potable process piping where corrosion resistance and flow control are required
• Drain, waste, and vent (DWV) systems with directional changes

Regulatory Insight

Lead-free copper fittings are required by code in all jurisdictions for systems carrying potable water. This product meets federal, state, and local requirements, including the Reduction of Lead in Drinking Water Act and California AB1953.

The 1-1/2” copper 45° elbow provides a durable and compliant solution for directional transitions in copper pipe systems. Its wrought copper construction, lead-free compliance, and compact design make it suitable for professional-grade water and mechanical piping installations across a range of building types and system layouts.
