1 inch x 3/4 inch Copper Reducing Coupling – For Code-Compliant Transitions in Copper Piping Systems

The 1 inch x 3/4 inch Copper Reducing Coupling is a solder-joint fitting used to connect copper tubing of dissimilar sizes in potable water, hydronic, or HVAC systems. Designed to ASTM and ANSI dimensional specifications, this coupling provides a secure, leak-resistant connection point while supporting compliance with current lead-free plumbing codes.

Manufactured from wrought copper, this coupling is suitable for pressure and non-pressure applications. Its uniform wall thickness, socket depth, and smooth interior provide optimal solder flow and reduce flow restriction at the transition point.

Key Performance Features

• ✅ Lead-Free Wrought Copper – Meets NSF/ANSI 61 and 372 for potable water applications in all jurisdictions.
• ✅ Socket x Socket Configuration – Designed for sweat connections with Type L or M copper tubing using standard soldering techniques.
• ✅ Consistent Sizing and Fit – Fabricated to tight manufacturing tolerances to reduce misalignment and ensure long-term joint integrity.
• ✅ Corrosion-Resistant Material – Copper resists scale buildup and degradation over time, even in hot water applications.

Technical Specifications

• Material: Lead-Free Wrought Copper
• Size: 1 inch nominal x 3/4 inch nominal
• Connection Type: Socket x Socket (sweat)
• Standards: Conforms to ASME B16.22 and ASTM B75/B88; NSF/ANSI 61 & 372 certified

Installation Guidance

Ensure pipe ends are cut square, reamed, cleaned, and fluxed prior to assembly. Apply lead-free solder suitable for potable water systems. Heating should be uniform to promote capillary action within the joint. Cooling must be gradual to prevent joint stress or cracking. Proper clearance, slope (where applicable), and code referencing should be maintained throughout the system layout.

Application Use

This reducing coupling is frequently used in water distribution lines, mechanical equipment tie-ins, and retrofit upgrades where downsizing is required. It is compatible with both horizontal and vertical orientations and is appropriate for concealed or exposed runs in residential, commercial, and institutional systems.

Regulatory Compliance

This fitting meets lead-free requirements under the Safe Drinking Water Act and is certified for use in all 50 states. It is recognized by the IPC, UPC, and local plumbing codes for pressure-rated potable and hydronic systems.

The 1 inch x 3/4 inch Copper Reducing Coupling provides a code-compliant, reliable transition between line sizes while maintaining full system integrity. Ideal for use in high-performance piping systems where fit precision and material longevity are critical.
