Hailiang 3/4x1/2rc Copper Reducing Coupling 3/4 X 1/2 Inch

Product Description

The HAILIANG 3/4x1/2rc is a copper solder-joint reducing coupling designed for pressurized water supply systems. It connects 3/4-inch OD copper tubing to 1/2-inch OD copper tubing using a capillary sweat (C x C) joint on both ends. Constructed from high-grade WROT copper, this fitting delivers consistent wall thickness and reliable joint integrity. It is manufactured to applicable ASME standards and meets NSF 61G requirements for potable water contact. Plumbers and pipefitters install this fitting during new construction, remodel work, or repair of above-ground domestic water distribution systems.

This reducing coupling is suited for above-ground potable water supply lines in residential and light commercial applications. It is used wherever a plumber needs to step down from a 3/4-inch main or branch line to a 1/2-inch supply run — common at fixture drops, appliance connections, and branch tee transitions. WROT copper construction ensures compatibility with standard copper tubing systems where soldered fittings are the specified joining method.

Key Features

• C x C solder-joint ends for standard sweat connection to copper tubing
• Reduces 3/4 inch OD to 1/2 inch OD in a single fitting
• WROT copper construction for consistent grain structure and pressure integrity
• Meets ASME B16.22 and related standards (B16.15, B16.18, B16.24, B16.50, B1.20.1)
• NSF 61G listed — suitable for above-ground potable water supply systems

Compatibility

Designed as an OEM-style solder-joint fitting for use in above-ground copper potable water supply and pressurized systems where ASME-standard WROT copper reducing couplings are required.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply line completely before cutting or fitting. Clean and flux both tube ends and fitting sockets before applying heat; use lead-free solder for all potable water applications. Allow the joint to cool undisturbed before restoring system pressure.
