1-1/2 inch Copper DWV Adapter Copper x Male

1-1/2 inch Copper DWV Male Adapter – Transition Fitting for Drain, Waste, and Vent Systems

The 1-1/2 inch Copper DWV Adapter is a solder joint x male-thread fitting used to transition from copper drain, waste, and vent (DWV) tubing to a female-threaded drainage connection. Constructed from wrought copper, this fitting is designed for use in non-pressurized gravity-flow systems and meets applicable ASTM and ASME standards for copper DWV installations.

It is typically used in horizontal or vertical DWV piping layouts and supports a secure joint between Type DWV copper tube and threaded components such as cleanouts, fittings, or mechanical devices in sanitary systems.

Performance Characteristics

• ✅ Wrought Copper Alloy: Manufactured to ASTM B75 standards for strength, dimensional stability, and corrosion resistance.
• ✅ Sweat x Male Threaded Configuration: Features a socket for copper tubing on one end and tapered male NPT threads on the other for connection to cast brass or copper alloy female-threaded fittings.
• ✅ DWV Rated: Intended for use in gravity-flow systems; not suitable for pressurized potable water lines.
• ✅ Lead-Free Compliance: Certified to NSF/ANSI 61 & 372 for low-lead requirements in building code-regulated environments.
• ✅ Standardized Dimensions: Conforms to ASME B16.29 specifications for copper DWV fittings.

Technical Specifications

• Material: Copper Alloy C12200
• Nominal Size: 1-1/2 inch
• Connection Type: Copper Socket x Male NPT Thread
• System Type: Drain, Waste, and Vent (non-pressurized)
• Standards: ASTM B75, ASME B16.29, NSF/ANSI 61 & 372

Installation Requirements

This adapter is installed by soldering the copper socket end to Type DWV copper tubing using approved lead-free solder and flux. The male threaded end should be tightened into a compatible female-threaded fitting with the use of pipe thread sealant or PTFE tape. Care must be taken not to overtighten and deform the threaded section. System testing should follow local code and authority-having-jurisdiction requirements.

Common Applications

Frequently used in sanitary DWV systems within residential, commercial, and institutional buildings. Typical locations include waste stack terminations, fixture drain branches, and transitions to mechanical cleanouts. Installed in accordance with IPC or UPC plumbing layouts.

Code Compliance Note

Copper DWV fittings must meet lead-free criteria and are restricted to use in non-pressurized drainage and venting systems. Always confirm proper sizing and compatibility during system design and rough-in stages.

The 1-1/2 inch Copper DWV Male Adapter provides a durable, code-compliant solution for adapting between copper tubing and threaded DWV components. Its consistent fabrication and tested material quality support long-term performance in gravity-flow drainage systems.
