3/4 inch x 1/2 inch Copper Reducing Adapter – Wrot Copper, Sweat x Sweat

The 3/4 inch x 1/2 inch Copper Reducing Adapter is a wrot copper fitting used to transition between two different nominal pipe sizes in soldered copper tubing systems. Manufactured in compliance with ASTM B75 and ASME B16.22, this adapter features cup (socket) ends sized for 3/4 inch and 1/2 inch copper tube and is designed for soldered connections in potable water, HVAC, and hydronic systems.

Formed from UNS C12200 copper alloy, the fitting delivers excellent thermal and corrosion resistance, making it suitable for long-term use in hot and cold water distribution, chilled water loops, and other low- to moderate-pressure fluid transport systems.

Specifications

• ✅ Material: Wrot copper (C12200, ASTM B75)
• ✅ Connection Type: Sweat x Sweat (Cup x Cup)
• ✅ Sizes: 3/4 inch x 1/2 inch nominal copper tube sizes
• ✅ Application: Pressure and gravity-fed copper tubing systems
• ✅ Standard Compliance: ASME B16.22, NSF/ANSI 61 & 372 (lead-free)

Application Areas

This copper reducing adapter is commonly used in professional plumbing and mechanical systems to reduce line size at branches, risers, or appliance transitions. Typical installations include:

• ✅ Domestic potable water systems
• ✅ Hydronic heating loops
• ✅ Chilled water and condenser water piping
• ✅ Transition points in retrofit and remodel work

Installation Guidelines

To install, prepare both pipe and fitting by cleaning with an abrasive cloth and applying lead-free flux. Use approved solder materials rated for potable water systems. Ensure full insertion and proper heating across the entire joint circumference to promote uniform solder flow. This fitting is suitable for systems operating within standard copper pressure and temperature ratings.

Key Performance Features

• ✅ Dezincification-Resistant: Wrot copper alloy resists pitting and corrosion in domestic water systems
• ✅ Reliable Pressure Seal: Cup depth and dimensions support capillary joint strength
• ✅ Lead-Free Certification: Complies with federal and state regulations for drinking water use
• ✅ Dimensional Accuracy: Manufactured to ensure precise joint fit and system compatibility

Regulatory Note

Conforms to current U.S. Safe Drinking Water Act (SDWA) requirements and is certified under NSF/ANSI 61 and 372 for use in potable water systems. Always verify component suitability with the local Authority Having Jurisdiction (AHJ).

The 3/4 inch x 1/2 inch Copper Reducing Adapter is a durable, code-compliant component ideal for professional-grade copper plumbing systems. Its high-integrity construction and precise tolerances help ensure long-lasting performance in both new construction and system retrofits.
