3 inch Copper DWV 90 Degree Street Elbow Copper x Fitting

3 inch Copper DWV 90° Street Elbow – Long Radius Fitting for Drainage Systems

The 3 inch Copper DWV 90° Street Elbow is a long-radius drainage fitting used to create a 90-degree directional change between copper drain, waste, and vent (DWV) piping. With a female (hub) x male (street) sweat configuration, it simplifies transitions by eliminating the need for a short pipe segment between fittings, making it ideal for compact installations and offset layouts.

This fitting is manufactured from wrought copper in accordance with ASME B16.29 and ASTM B75/B88 material standards. Designed specifically for use in gravity-flow DWV systems, it is not intended for use in pressurized supply lines. The smooth internal bore supports efficient flow with minimal turbulence or blockage risk.

Technical Specifications

• Material: Wrought Copper (typically Alloy C12200)
• Size: 3-inch nominal diameter
• Connection Type: Female sweat x Street (male sweat)
• Standards: ASME B16.29, ASTM B75/B88, NSF/ANSI 61 & 372 (lead-free)
• Application: Drain, Waste, and Vent (DWV) systems – non-pressurized only

Performance Features

• ✅ Street Elbow Configuration – Connects directly to another fitting without the need for a coupling or section of pipe.
• ✅ Long Radius Bend – Reduces flow restriction and helps prevent solids accumulation in horizontal drain lines.
• ✅ Sweat Socket Ends – Compatible with standard copper tube and lead-free solder or brazing methods.
• ✅ Corrosion Resistance – Maintains structural and mechanical integrity in wastewater environments.
• ✅ Code-Compliant Construction – Suitable for use in systems requiring lead-free components under the Safe Drinking Water Act (SDWA).

Installation Guidelines

Clean and deburr mating surfaces. Apply appropriate flux and solder, using standard copper joining methods. Allow for thermal expansion during system design. Street elbows must be properly oriented to prevent improper pitch or misalignment. Use in DWV applications only—do not install in pressurized water lines.

Common Applications

This 90° street elbow is typically installed in horizontal-to-vertical drain transitions, fixture arms, and tight layout changes in residential and commercial DWV systems. It is often used in wall cavities and floor penetrations where minimizing fitting length is essential.

Regulatory and Code Note

Copper DWV fittings must be third-party certified for lead-free compliance in applicable jurisdictions. Always verify system compatibility before use. This product is not suitable for potable or pressurized applications.
