1-1/4 inch Copper DWV 90 Degree Elbow Copper x Copper

1-1/4 inch Copper DWV 90° Elbow – CxC Long-Turn Fitting for Drain, Waste, and Vent Applications

The 1-1/4 inch Copper DWV 90° Elbow is a solder-joint fitting designed to provide a smooth directional change in non-pressurized copper drain, waste, and vent (DWV) systems. Constructed from lead-free wrought copper, this elbow is configured with copper socket (CxC) ends and a long-radius sweep to promote flow efficiency and reduce turbulence in gravity drainage lines.

Manufactured to meet ASME and ASTM standards, this fitting is suitable for horizontal and vertical installations in above-ground residential or commercial DWV systems where durability, corrosion resistance, and proper hydraulic flow path are essential.

Product Features

• ✅ Material: Wrought copper, typically alloy C12200, compliant with ASTM B75/B88
• ✅ Connection Type: Copper x Copper solder cup ends
• ✅ Fitting Design: Long-turn 90-degree sweep elbow for optimal flow direction and reduced velocity loss
• ✅ System Use: Designed specifically for low-pressure DWV systems; not for use in pressurized water distribution
• ✅ Compliance: Meets ASME B16.29 and NSF/ANSI 61 & 372 for lead-free system components

Installation Guidance

This elbow is intended for soldered copper tubing installations. All joining surfaces should be cleaned and fluxed prior to assembly. Apply uniform heat with an approved torch to allow lead-free solder to fully flow into the joint per capillary action. Allow sufficient cooling time before applying system pressure or conducting leak tests. Not intended for pressurized or gas applications.

Applications

Commonly installed in horizontal or vertical DWV lines behind walls, under floors, or in ceiling assemblies. Frequently used in branch connections and fixture arm installations where a smooth change in direction is required to maintain proper drainage and venting functions.

Standards and Code Compliance

This fitting complies with national plumbing code requirements for copper DWV fittings, including IPC, UPC, and model building codes referencing ASME B16.29. It is accepted for use in sanitary drainage systems requiring corrosion-resistant, flame-soldered copper connections.
