2 inch Copper DWV 90° Elbow – Long Radius Fitting for Drain, Waste, and Vent Applications

The 2 inch Copper DWV 90° Elbow is a solder joint fitting designed for directional changes in non-pressurized copper drain, waste, and vent (DWV) systems. Manufactured from wrought copper and compliant with ASTM and NSF standards, this elbow provides a smooth radius turn to maintain consistent flow and minimize system turbulence in gravity-fed piping layouts.

It is intended for use with soldered copper tubing in above-ground sanitary drainage systems, providing mechanical integrity and corrosion resistance in both residential and commercial building infrastructure. This fitting is lead-free and suitable for systems requiring code-compliant materials for public health and safety.

Key Attributes and Functional Design

• ✅ Wrought Copper Construction – Type DWV copper provides formability and corrosion resistance, ensuring long-term durability in drainage environments.
• ✅ Soft-Sweep Radius – 90° long-turn configuration reduces flow resistance and helps minimize clogs or flow noise in horizontal-to-vertical transitions.
• ✅ Solder Cup Ends – End connections are sized for sweat soldering to standard copper DWV tubing per ASME B16.29.
• ✅ Lead-Free Compliant – Meets NSF/ANSI 61 and 372 standards; acceptable for use in applications governed by federal low-lead laws.
• ✅ Non-Pressure Rated – Designed exclusively for use in gravity drainage systems; not intended for water distribution or pressurized service.

Technical Specifications

• Nominal Size: 2”
• Connection Type: Female Solder (C x C)
• Material: Wrought Copper (typically Alloy C12200)
• Standard Compliance: ASME B16.29, ASTM B75, NSF/ANSI 61 and 372
• Application: Drainage, Waste, and Vent (DWV) Systems Only

Installation Guidelines

This fitting must be joined using lead-free solder and flux approved for copper tubing in accordance with local plumbing codes. Tubing should be properly cleaned, reamed, and dry-fit prior to soldering. Heating must be applied uniformly to achieve full capillary action. Not for use with pressurized potable water systems or hydronic lines.

Application Use Cases

Commonly installed in horizontal-to-vertical DWV pipe transitions, branch offsets, and behind-wall sanitary layouts. Suitable for residential, commercial, and institutional systems utilizing copper tubing for waste drainage or vent piping.

Code Compliance Insight

Use of lead-free copper fittings in DWV systems is required under the Safe Drinking Water Act (SDWA) when installed in proximity to potable systems or in buildings governed by low-lead mandates. This fitting complies with those requirements.

The 2 inch Copper DWV 90° Elbow is a high-integrity, code-approved component for sanitary drainage systems. Designed for directional changes in copper DWV lines where long-term performance and regulatory compliance are required.
