Nibco Inc W00765T 3/4x1/2 Cxc Reducing Coupling

Product Description

The NIBCO INC W00765T is a lead-free copper reducing coupling designed to connect a 3/4-inch tube to a 1/2-inch tube using a sweat (solder) connection on both ends. The fitting features solder cups on each end, allowing licensed plumbers to make a clean, pressure-rated joint with standard soldering tools and technique. This type of reduction coupling is a core component in copper water supply and distribution systems where pipe sizing changes occur at branch points, fixture connections, or equipment inlets. The lead-free construction meets current regulatory requirements for potable water service.

This coupling is used in residential and light commercial plumbing installations where a copper tube run steps down from 3/4-inch to 1/2-inch. Typical applications include domestic cold and hot water supply lines, branch runs to fixtures, and connections to appliances or fixtures that require 1/2-inch inlet piping. The CxC (copper by copper) configuration requires soldering both joints, making it a permanent, reliable mechanical connection suited for in-wall, under-slab, or exposed piping installations.

Key Features

• Lead-free construction compliant with potable water regulations
• Solder cup ends on both inlet and outlet for sweat connection
• CxC (copper by copper) configuration — no threads or compression hardware required
• Reduces 3/4-inch tube to 1/2-inch tube in a single fitting
• Sold in packages of 25 units per package quantity

Compatibility

Designed as an OEM-style replacement and standard-use fitting compatible with 3/4-inch and 1/2-inch copper tubing in sweat-joint plumbing systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off the water supply and fully drain the line before cutting or soldering. Clean and flux both the tube ends and solder cups before applying heat to ensure a sound joint. Avoid overheating the fitting, as excessive heat can damage the cup seating surface.
