Ndl Industries W1050 Copper Reducing Coupling 1-1/8x3/4 Cxc

Product Description

The NDL INDUSTRIES W1050 is a copper reducing coupling designed to transition between two different pipe diameters in a sweat-soldered copper piping system. Sized at 1-1/8 inches by 3/4 inches with a C x C (copper-to-copper) connection type, this fitting accepts standard copper tubing on both ends and is joined using a torch and solder. It is a standard plumbing fitting installed by licensed plumbers and pipefitters working on water supply, refrigerant, or hydronic systems where a diameter reduction is required inline.

This reducing coupling is suited for residential and light commercial plumbing and mechanical applications. It is commonly used when transitioning from a larger copper main to a smaller branch line, or when replacing a damaged section of pipe that requires a size change. The C x C connection type makes it compatible with standard sweat-soldering procedures using lead-free solder per applicable plumbing codes.

Key Features

• Reduces from 1-1/8 inches to 3/4 inches in a single fitting
• C x C connection type for standard sweat-solder installation
• Copper construction for corrosion resistance and long service life in wet systems
• Sold in a box quantity of 25, suitable for job-site stocking

Compatibility

Designed as an OEM-style replacement or new-installation fitting for copper piping systems requiring an inline reduction from 1-1/8 inches to 3/4 inches with sweat-solder connections.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using a torch, lead-free solder, and flux per local plumbing code requirements such as the IPC or applicable state amendments. Shut off the water supply and fully drain the line before cutting and fitting. Ensure pipe ends are clean, deburred, and properly fluxed before applying heat to achieve a full, leak-free solder joint. Do not overheat the fitting, as excessive heat can burn flux and compromise the joint.
