Nibco Inc W00700D Wrot Copper Coupling with Stop 3/8 Cxc

Product Description

The NIBCO INC W00700D is a wrot copper sweat coupling with an integral dimple stop, designed for connecting two lengths of copper tubing in a continuous run. The fitting ships in the C600 CxC configuration, meaning both ends accept standard copper tube for solder-cup (sweat) connections. The built-in dimple stop positions each tube end at the correct insertion depth, ensuring consistent solder joint quality and eliminating guesswork during assembly. This fitting is lead-free, meeting regulatory requirements for potable water applications. Plumbers and pipefitters install this coupling on residential and light commercial water supply lines, hydronic heating systems, and general copper distribution piping.

This coupling is suited for residential and commercial plumbing installations where two straight sections of 3/8 inch copper tube must be joined. Common applications include water supply rough-in, branch line extensions, and repair of damaged tubing sections. The sweat connection method is standard practice in copper pipework, and the dimple stop feature supports uniform joint depth across high-volume installation work. This fitting is sold in a package quantity of 25 units, making it practical for service trucks and wholesale distribution to plumbing contractors.

Compatibility

Designed as an OEM-style wrot copper sweat fitting compatible with standard 3/8 inch copper tube in CxC (solder cup by solder cup) configurations for potable water and general plumbing systems.

Installation Notes

Installation is performed by licensed plumbers following applicable IPC and local plumbing code requirements. Shut off and drain the water supply before cutting or preparing tube ends. Clean and flux both tube ends and the fitting sockets thoroughly before applying heat to ensure a sound, void-free solder joint. Do not use open flame near combustible materials without a heat shield, and allow joints to cool fully before restoring system pressure.
