2 inch Copper DWV Adapter Copper x Male

2 inch Copper DWV Male Adapter – Precision-Fit for Drainage Applications

The 2 inch Copper DWV Male Adapter is designed to transition copper drainage piping to threaded connections in waste, vent, and drain systems. This fitting is machined from wrought copper and features a sweat (cup) connection on one end and male pipe threads (MPT) on the other, allowing for a secure transition between copper tubing and threaded fittings or valves in DWV systems.

Product Benefits

• Wrought Copper Body: Provides excellent corrosion resistance and long service life under typical DWV system conditions.
• Lead-Free Compliance: Manufactured from low-lead copper alloy, suitable for use in systems requiring code-compliant, safe fittings.
• Consistent Dimensions: Adheres to ASME B16.29 and NSF/ANSI 61/372 standards for dimensional accuracy and performance.
• Sweat x Male Thread: Makes it easy to join copper DWV tubing to threaded brass or cast iron fittings in vertical or horizontal piping configurations.
• Low-Pressure Rated: Specifically designed for non-pressurized drain, waste, and vent systems where soldering is the preferred joining method.

Technical Specifications

• Material: Wrought Copper (Lead-Free)
• Size: 2 inches nominal
• End Connections: Cup x Male NPT
• Applicable Standards: ASME B16.29, NSF/ANSI 61 and 372
• Application Type: DWV (Drain, Waste, Ventilation) Systems

Installation Considerations

Install using standard copper DWV soldering practices. Clean and flux both mating surfaces, then apply lead-free solder to form a watertight seal at the sweat connection. For the male threaded end, apply a compatible pipe joint compound or PTFE tape to achieve a secure threaded seal. Designed for gravity-flow systems, this fitting is not pressure-rated and should not be used in potable or pressurized applications.

Common Applications

Used in horizontal and vertical DWV copper tubing systems, this male adapter is commonly found in residential, commercial, and institutional buildings where a transition is required between copper pipe and cast iron, galvanized, or brass-threaded components. Typical placements include soil stacks, branch vents, and waste lines.

Did You Know?

Unlike pressure-rated copper adapters, DWV adapters are engineered for drainage systems only. They feature different wall thickness and joining requirements tailored to gravity systems where flow, not pressure, is the primary design consideration.

For drainage systems requiring secure copper-to-threaded transitions, the 2 inch Copper DWV Male Adapter offers reliable performance, code-compliant construction, and easy integration into existing copper or mixed-material layouts.
