1-1/4 inch Copper 45 Degree Street Elbow Type DWV Copper x Fitting

1-1/4 inch Copper 45° Street Elbow – DWV Fitting for Directional Transitions

The 1-1/4 inch Copper 45° Street Elbow is designed for use in Drainage, Waste, and Vent (DWV) systems where a smooth directional change is needed. This street elbow features a hub x street (spigot) connection, allowing it to join directly to another fitting without the need for additional pipe segments. It is ideal for applications requiring compact configurations or precise routing in confined spaces.

Advantages for Professional Installation

• ✔️ Street End Design – Reduces fitting-to-fitting distance and simplifies tight layouts by eliminating intermediate pipe lengths.
• ✔️ Clean Transition – Provides a gradual 45-degree change in direction, minimizing flow turbulence in DWV systems.
• ✔️ Rigid Copper Construction – Fabricated from wrought copper to ensure dimensional consistency, corrosion resistance, and long-term system integrity.
• ✔️ Lead-Free Compliance – Meets all national and state plumbing codes mandating the use of lead-free materials in potable and waste systems.
• ✔️ Sweat Connection Method – Designed for soldering into copper piping systems, providing a permanent, leak-free bond when properly installed.

Application and Use Cases

This copper DWV 45° street elbow is typically installed in horizontal or vertical drainage runs to redirect flow with minimal resistance. Its compact form factor is especially useful in wall cavities, ceiling spaces, and fixture branches where traditional elbows would increase system length or require additional fittings.

Did You Know?

Street elbows are engineered to reduce the total number of joints in a DWV line, helping to preserve slope and clearance in designs with limited dimensional tolerance. Their use can also help minimize labor and material costs in multi-fitting configurations.

For dependable performance in copper DWV systems, the 1-1/4 inch Copper 45° Street Elbow delivers code-compliant, job-ready functionality. Its dimensional precision and corrosion resistance make it a preferred choice among plumbing professionals working in both new construction and renovation environments.
