1-1/2 inch Copper DWV Coupling – Precision Fit for Drainage Systems
The 1-1/2 inch Copper DWV Coupling is engineered for use in non-pressurized drainage, waste, and vent piping systems. Its seamless copper construction offers corrosion resistance and thermal durability, making it a dependable choice for professionals working in both residential and commercial projects.
Performance Features
- Seamless Copper Body – Fabricated from high-grade copper suitable for gravity-flow DWV applications.
- DWV Designation – Intended for systems that do not require pressure resistance, with ends configured for soldered connections.
- Lead-Free Compliance – Meets current U.S. lead-content regulations for potable and non-potable systems.
- Thermal Compatibility – Maintains performance under temperature fluctuations typical in DWV systems.
- Code-Conforming Dimensions – Manufactured to ASTM B306 and ANSI/ASME B16.29 standards for copper drainage fittings.
Specifications
- Nominal Size: 1-1/2 inch
- Material: C12200 copper
- Type: Coupling, DWV pattern
- Ends: Solder (female)
- Standards: ASTM B306, ANSI/ASME B16.29, NSF/ANSI 61-G compliant
Typical Applications
Used in horizontal and vertical DWV systems to connect sections of 1-1/2 inch copper pipe. Common in sanitary systems behind walls, beneath floors, or overhead in commercial buildings. Also suitable for joining copper branches in renovation work where pipe replacement is necessary.
Installation Note
Designed for use with lead-free solder and appropriate flux. Ensure pipe ends are properly cleaned and prepped prior to sweating. Avoid use in pressurized systems, as DWV fittings are not designed for such applications.
Professional Insight
Copper DWV fittings continue to be a preferred solution for code-compliant waste systems due to their longevity and minimal thermal expansion. They offer quiet operation compared to plastic systems and retain fire-resistance ratings in commercial construction environments.
