Elkhart Products COU-112 Copper Coupling 1-1/2 in Cxc

Product Description

The ELKHART PRODUCTS COU-112 is a WROT copper coupling with stop, sized at 1-1/2 inches for C x C (copper-to-copper) solder connections. The internal stop positions pipe ends consistently during assembly, ensuring a repeatable solder joint depth every time. Manufactured from WROT copper, this fitting meets the dimensional and material standards expected in professional plumbing installations. It is a standard sweat-fit coupling used by licensed plumbers in both new construction and repair work on copper water supply and hydronic piping systems. The fitting weighs 0.216 pounds and has an overall length of 1.74 inches.

This coupling is suited for residential and light commercial plumbing applications where copper tubing is joined by soldering. Typical uses include water supply lines, heating system piping, and general copper distribution work. The C x C end configuration accepts standard copper tube on both ends, making it straightforward to use in straight-run extensions or repair sections. Installation follows standard sweat-soldering practice and is performed by licensed plumbers or qualified pipefitters.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off and drain the water supply before cutting into any existing line. Clean tube ends and fitting sockets with emery cloth or a fitting brush, apply flux, and solder per IPC and local code requirements. Do not apply excessive heat to the fitting body — follow standard sweat-soldering practice to avoid damaging the stop or compromising the joint.
