Ndl Industries W1084 Copper Reducing Coupling C X C

Product Description

The NDL INDUSTRIES W1084 is a copper reducing coupling designed to join two copper tubes of different diameters in a sweat-solder (C x C) connection. The larger end accepts 2.625-inch copper tube and the smaller end accepts 1.625-inch copper tube. This fitting is used wherever a supply run must step down to a smaller branch line, making it a standard component in copper piping systems. Licensed plumbers and HVAC installers handle this type of fitting during new construction, retrofit, or repair work on water supply, hydronic heating, or refrigeration piping.

This reducing coupling is suited for residential and light commercial copper piping applications where a size transition is required in-line. The C x C connection style means both ends are sweat-solder joints, requiring proper flux application, torch work, and solder fill to complete the connection. It ships in a box quantity of 12, making it practical for contractors stocking multiple fittings for a project or service vehicle.

Key Features

• Copper construction for reliable, corrosion-resistant performance in plumbing and HVAC piping
• Reducing profile transitions from 2.625-inch to 1.625-inch tube diameter in a single fitting
• C x C connection type — both ends are sweat-solder joints for a leak-tight, permanent connection
• Box quantity of 12 supports multi-fitting job requirements

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper tube systems using standard 2.625-inch and 1.625-inch outside-diameter copper tube with sweat-solder end connections.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Shut off and depressurize the supply line and allow any remaining fluid to drain before cutting into an existing system. Clean and flux both tube ends and the fitting sockets fully before applying heat, and follow local plumbing codes — typically aligned with the IPC or applicable state code — for approved solder alloys and flux materials. Do not overheat the fitting, as excess heat can damage the copper or wick solder away from the joint.
