3 inch Copper DWV 45 Degree Elbow Copper x Copper

3 inch Copper DWV 45° Elbow – Built for Code-Compliant Drainage Systems

The 3 inch Copper DWV 45° Elbow is engineered for smooth directional changes in drainage, waste, and vent systems. Designed for gravity-flow applications, this elbow enables efficient transitions while maintaining consistent flow characteristics and structural integrity.

Key Performance Features

• ✅ DWV System Compatibility Manufactured to meet copper DWV standards for non-pressurized waste systems.
• ✅ 45° Bend Radius Supports gradual directional shifts in piping runs, minimizing flow disruption and reducing turbulence.
• ✅ Soldered Connection Ends are sized for sweat (cup) connections using lead-free solder, ensuring a permanent, sealed joint.
• ✅ Corrosion-Resistant Copper Fabricated from durable, lead-free wrought copper that resists scale and corrosion over time.
• ✅ Code-Ready Material Complies with applicable plumbing codes and is suitable for use in residential and commercial DWV installations.

Installation Details

This elbow is installed using conventional soldering methods. Prior to assembly, clean and flux all mating surfaces. Use only lead-free solder to ensure compliance with UPC and IPC regulations. Proper support and spacing should be observed to maintain slope and prevent stress on the joints.

Product Specifications

Typical Use Cases

Commonly installed in horizontal and vertical DWV piping to navigate structural constraints or align with fixture drains. Also used in multi-story residential and light commercial buildings where copper DWV systems are specified for acoustic and corrosion performance.

Note for Contractors

Ensure joints are free of moisture before soldering and allow adequate expansion space when installed in longer runs. For fire-rated assemblies, verify that copper DWV elbows are used with approved firestopping systems.

Engineered for reliability and ease of use, this 3 inch Copper DWV 45° Elbow provides durable performance and long-term system integrity in waste and vent piping layouts.
