2 inch x 3/4 inch Copper Reducing Coupling – For Transitioning Copper Tube Sizes in Pressurized Systems

The 2 inch x 3/4 inch Copper Reducing Coupling is a precision-fabricated fitting used to join copper tubing of different diameters in fluid distribution systems. Designed for solder (sweat) connections, this coupling ensures mechanical stability and long-term reliability in both residential and commercial applications where pipe size reduction is required.

Manufactured from lead-free copper in accordance with ASTM standards, the coupling provides excellent corrosion resistance, structural integrity, and compatibility with standard copper tube sizing. It is suitable for installation in potable water, hydronic heating, and other pressure-rated piping systems.

Performance Features

• ✅ Precision Machined – Tight tolerances ensure consistent insertion depth and capillary flow during soldering.
• ✅ Corrosion-Resistant Material – High-purity copper withstands chemical and environmental exposure common to plumbing systems.
• ✅ Uniform Wall Thickness – Promotes structural integrity and smooth fluid flow through transition points.
• ✅ Compact Profile – Ideal for installations in tight spaces or retrofit applications requiring minimal added length.
• ✅ Code Compliant – Lead-free and approved for use in potable water systems per federal and state plumbing codes.

Installation Guidelines

This coupling is designed for use with copper pipe in soldered systems. Both pipe ends and fitting sockets should be reamed, cleaned, and fluxed prior to assembly. Even torch heating is required to achieve proper capillary fill. For pressure applications, the system should be pressure-tested following installation per local plumbing code. Thread sealants and plumber’s tape are not applicable for sweat joints.

Technical Specifications

• Nominal Size: 2 inch x 3/4 inch
• Material: Lead-Free Copper (ASTM B88 compliant)
• Connection Type: Copper x Copper (Sweat)
• Pressure Rating: Suitable for standard pressurized water systems

Applications

Commonly used in potable water distribution lines, branch reductions, and boiler return lines where a 2 inch main needs to transition to a 3/4 inch service or fixture supply. Also applicable in hydronic heating systems, mechanical rooms, and remodels where adapting existing copper pipe layouts is required.

Regulatory Compliance

This product meets lead-free requirements under the Safe Drinking Water Act and is compliant with ANSI/NSF 61-G standards. Approved for use in all jurisdictions requiring lead-free fittings for potable water systems.

The 2 inch x 3/4 inch Copper Reducing Coupling is a code-compliant, durable fitting designed for contractors who require reliable and repeatable results in fluid system transitions. Its compatibility with standard copper tubing and robust construction make it a staple in professional-grade plumbing installations.
