Nibco Inc W00980D 1 Inch Cxc Coupler No Stop

Product Description

The NIBCO INC W00980D is a 1-inch copper CxC coupler with no stop, designed for sweat-solder connections in residential and commercial plumbing systems. It features solder cups on both ends and omits the internal stop, allowing the fitting to slide freely along tubing — a critical advantage when repairing an existing run where a fixed stop would prevent full insertion. The fitting is lead-free, meeting current potable water requirements. Licensed plumbers and pipefitters install this type of coupler when splicing or repairing copper water supply lines.

This fitting is suited for standard copper tube repair and connection work in potable water, hydronic heating, and general plumbing distribution systems. The no-stop design is especially useful in tight repair scenarios where the tube ends cannot be pulled apart enough to seat a standard coupler with an internal shoulder. It accepts 1-inch copper tubing on both ends using a sweat-solder joint.

Key Features

• No internal stop allows free sliding along tubing for repair applications
• Solder cup ends on both sides for standard sweat connections
• Lead-free construction meets potable water code requirements
• 1-inch CxC configuration connects or repairs two lengths of copper tube
• Sold individually; package quantity of 30 available

Compatibility

Designed as an OEM-style sweat fitting for use with standard 1-inch copper tubing in residential and commercial plumbing installations.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and fully drain the line before cutting or fitting. Clean and flux all mating surfaces before applying heat; use a properly sized torch and lead-free solder rated for potable water service. Do not apply flux or heat to a pressurized or wet line.
