2 inch Copper DWV Reducing Adapter Fitting x Female

2 inch Copper DWV Reducing Adapter – Designed for Code-Compliant Transitions

The 2 inch Copper DWV Reducing Adapter is a precision-formed fitting built to transition between dissimilar copper pipe sizes within Drain, Waste, and Vent (DWV) systems. Its smooth-walled interior and exact tolerances allow for streamlined flow and consistent performance in non-pressurized environments.

Application and Performance

Manufactured from high-grade, lead-free wrought copper, this adapter is engineered for durability and compatibility with standard DWV solder-joint systems. It enables a reduction from a larger copper tube size to a smaller one, maintaining system integrity while conforming to dimensional standards as outlined by ASME and ASTM specifications.

Key Advantages

• Standard Compliance: Conforms to ASME B16.29 and applicable ASTM standards for DWV copper fittings.
• Material: Wrought copper, lead-free alloy composition ensures compliance with current U.S. plumbing codes.
• Connection Type: Female solder cup x reduced-size female solder cup for smooth, uniform soldering and tight fit-up.
• Non-Pressurized Use: Rated for gravity-flow applications in sanitary drainage and vent piping.

Installation Notes

Install using standard copper soldering practices. Ensure surfaces are clean and fluxed prior to applying heat. This adapter is not intended for use in pressurized water distribution or hydronic heating systems. For horizontal or vertical DWV layouts, verify slope and alignment to support unobstructed flow and code compliance.

Typical Applications

Used in multi-branch DWV piping networks, particularly where space constraints or fixture layout necessitate a size change within copper tubing. Commonly installed in residential and commercial DWV systems behind walls, in floors, or overhead runs.

Technical Data

• Nominal Size: 2 inch x reduced outlet (varies by specification)
• Material Standard: ASTM B75/B88 or equivalent
• Configuration: Female solder x female solder (reduced)
• Plumbing Code: Lead-free compliant; suitable for non-pressure DWV systems

Material Insight

DWV copper fittings are produced with thinner walls than water supply-grade fittings, minimizing weight while retaining mechanical strength for venting and waste applications. This allows for simplified handling and quicker installation without compromising structural reliability.

The 2 inch Copper DWV Reducing Adapter is a dependable choice for professionals managing waste and vent transitions in copper systems. It delivers consistent performance where size reduction and code compliance are critical.
