Mueller Streamline CPL00892 Copper Coupling 1 in C X C

Product Description

The MUELLER STREAMLINE CPL00892 is a straight wrot copper sweat coupling designed for permanent, pressure-rated connections in residential and commercial plumbing systems. The fitting accepts 1-inch copper tube on both ends using a C x C (solder) connection, making it a standard choice for copper supply line repairs, extensions, and new installations. At 0.11 pounds and measuring 1.91 inches in length with a 1.21-inch profile, this compact fitting handles tight rough-in conditions without difficulty. Plumbers and pipefitters rely on wrot copper for its consistent wall thickness, high-pressure performance, and compatibility with standard lead-free solder and flux.

This coupling is suited for potable water supply lines, hydronic heating loops, and general plumbing distribution systems in both residential and light commercial applications. The straight configuration allows tube-to-tube joining in a continuous run without any offset. It is typically installed during copper rough-in, repair splices, or when adding branch points to an existing main. This fitting meets the dimensional standards expected by plumbers working to IPC and UPC code requirements for copper sweat fittings.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off the water supply and fully drain the line before cutting and deburring the tube ends. Clean both tube ends and the fitting socket with emery cloth and apply lead-free flux before soldering.
