3 inch Copper DWV 90 Degree Elbow Copper x Copper

3 inch Copper DWV 90° Elbow – CxC Sweat Fitting for Drainage Applications

The 3 inch Copper DWV 90-Degree Elbow with CxC (copper x copper) sweat connections is designed for use in non-pressurized drain, waste, and vent (DWV) piping systems. This fitting enables a 90° directional change in horizontal or vertical DWV layouts and is engineered to maintain consistent flow characteristics while meeting industry standards for dimensional and structural performance.

Product Features

• Type: DWV 90° elbow for copper tubing
• Size: 3 inch nominal pipe size
• Connection: Cup (CxC) ends for soldered joints
• Material: Wrought copper, lead-free alloy
• Compliance: Meets ASME B16.29 and NSF/ANSI 61 & 372 for lead-free applications

Intended Use

This elbow fitting is intended for use in DWV systems within residential and commercial buildings. It is typically installed in horizontal or vertical configurations behind walls, under floors, or above ceilings to route drainage or vent lines around structural obstacles or corners. It is not suitable for pressurized water or gas applications.

Installation Notes

Install using standard copper soldering procedures. Ensure pipe ends are properly cleaned and fluxed. Apply solder once joint is heated adequately. Allow joints to cool naturally before testing. Use of approved lead-free solder and flux is required for compliance with potable water standards, even in DWV systems.

Performance Characteristics

• Corrosion Resistance: Copper provides excellent resistance to corrosion from domestic waste and vent gases.
• Thermal Durability: Maintains shape and seal integrity in high-temperature venting environments.
• Smooth Interior: Facilitates consistent flow with minimal turbulence or blockage risk.

Applications

• Residential DWV piping systems
• Commercial copper drain and vent lines
• Code-compliant retrofit and new construction installations

Regulatory Note

Lead-free copper fittings are required by plumbing codes for use in all potable water systems, and many jurisdictions apply this standard to DWV components as well. Always confirm product suitability with local code authorities.

Using a properly certified copper DWV elbow ensures safe, compliant, and long-lasting drainage performance in modern plumbing systems. This 3 inch 90° fitting supports efficient pipe routing while minimizing the risk of failure over time.
