Heavy-Duty Copper Reducing Adapter – 1 inch x 3/4 inch Sweat x Sweat

The 1 inch x 3/4 inch Copper Reducing Adapter is built to provide dependable transitions between copper tubing sizes in potable water and hydronic applications. Manufactured from lead-free copper alloy, this fitting supports consistent system performance and compliance with modern plumbing code requirements.

Product Benefits

• ✅ Lead-Free Copper Construction – Suitable for drinking water systems and meets federal low-lead content requirements (NSF/ANSI 61 & 372).
• ✅ Sweat Connection – Standard solder joint design for secure joining with Type M or L copper tubing.
• ✅ Precision-Formed Sizing – Smooth internal diameter transition ensures balanced flow with minimal turbulence or pressure loss.
• ✅ Corrosion-Resistant Material – Maintains mechanical integrity in high-humidity or aggressive water environments.
• ✅ Code-Compliant Fit – Manufactured in accordance with ASME B16.22 for wrought copper and copper alloy solder-joint pressure fittings.

Technical Specifications

• Material: Lead-Free Copper (Alloy C12200)
• End Connections: 1 inch Sweat x 3/4 inch Sweat
• Max Working Pressure: 200 PSI (soldered connection, 100°F)
• Applicable Tubing Types: Type M, L, or K hard copper
• Compliance: NSF/ANSI 61, NSF/ANSI 372, ASME B16.22

Installation Considerations

Install using standard soldering procedures with flux and lead-free solder. Ensure pipe ends are deburred and cleaned before assembly. Use nitrogen purge during brazing in closed-loop systems to prevent oxidation. Final inspection should include a pressure test per local code requirements.

Typical Applications

Commonly used in domestic water supply lines, hydronic heating circuits, and mechanical equipment transitions. This fitting is essential for adapting between main line feeds and branch piping in both residential and light commercial construction.

Industry Insight

As of the Reduction of Lead in Drinking Water Act, effective January 2014, all plumbing fittings used for potable systems must meet low-lead compliance—this copper adapter does.
