1-1/4” Copper DWV 45° Elbow – For Precision Turns in Drainage Systems

The 1-1/4” Copper DWV 45° Elbow is a critical component designed for directing the flow in drain, waste, and vent (DWV) systems where space and alignment demand a precise 45-degree directional change. Its smooth interior radius and durable copper construction help reduce flow resistance and noise, contributing to efficient system performance.

Performance Advantages

• Material Composition: Manufactured from wrought copper, this elbow delivers proven resistance to corrosion and scale buildup in non-pressurized drainage applications.
• 45-Degree Sweep: Designed to create gentle turns that support proper flow direction, reducing the risk of sediment accumulation and blockages.
• Socket x Socket Ends: Fits snugly into DWV copper tubing, allowing for secure soldered joints that minimize potential leak paths.
• Lead-Free Compliance: Meets ASTM B75 and ASME/ANSI B16.29 specifications for lead-free fittings suitable for modern building codes.

Technical Specifications

• Size: 1-1/4 inch nominal pipe size
• Angle: 45 degrees
• Connection Type: Copper x Copper (sweat/socket)
• Standards: ASTM B75, ASME B16.29, NSF/ANSI 61 compliant
• Intended Use: Gravity-fed DWV systems – not for use in pressurized applications

Installation Considerations

• Use proper cleaning and fluxing tools prior to soldering to ensure solid capillary joint bonding.
• Apply a torch evenly across the joint during soldering for uniform heat distribution and secure sealing.
• Allow cooling and visual inspection for voids or excessive solder buildup that may impede flow.

Common Applications

This copper elbow is typically installed in horizontal and vertical DWV lines, particularly in wall cavities, under slab assemblies, and multi-branch configurations. Its 45° turn minimizes turbulence compared to sharper directional changes, helping to meet code requirements in residential and commercial buildings.

Did You Know?

Copper DWV fittings are highly resistant to microbial growth and can help maintain sanitary conditions in plumbing systems over time. Their long service life also makes them an economical choice for infrastructure projects where access post-installation is limited.

Built for accuracy and compliance, the 1-1/4” Copper DWV 45° Elbow delivers consistent results in drainage systems requiring directional flow management. Ideal for applications demanding reliability, smooth transitions, and a proven material profile.
