Nibco Inc W00837T Reducing Coupling 1-1/4 X 1 Inch Cxc

Product Description

The NIBCO INC W00837T is a lead-free copper reducing coupling designed to connect a larger-diameter copper tube to a smaller-diameter copper tube using solder-cup ends. Configured as a 1-1/4 inch by 1 inch connection in a CxC (cup by cup) end pattern, this fitting is part of the U600 product line and is built for sweat-solder installation by licensed plumbers and pipefitters. Weighing approximately 0.96 pounds per package of five, it is a standard-inventory fitting suited for residential and light commercial plumbing systems.

This reducing coupling is used wherever a copper tube run changes from 1-1/4 inch to 1 inch diameter. Common applications include domestic water supply lines, recirculation loops, and branch connections in both new construction and retrofit work. The CxC configuration accepts standard copper tubing on both ends and is compatible with conventional sweat-solder joining methods using lead-free solder, making it suitable for potable water service where lead-free compliance is required by code.

Installation Notes

Installation is performed by a licensed plumber or pipefitter using standard sweat-solder technique. Shut off the water supply and fully drain the line before cutting and fitting. Clean all mating tube ends and fitting cups with emery cloth and apply lead-free flux before applying heat.
