The MUELLER STREAMLINE CPL00874 is a straight solder coupling manufactured from wrot copper for use in small-bore copper tubing systems. It connects two copper tube ends using a C x C (sweat) joint, forming a permanent, pressure-rated union. At 0.5 inches wide and 1.36 inches in length, this compact fitting is suited for tight spaces and precision plumbing work. It meets ASME and NSF compliance standards, making it appropriate for potable water applications. Licensed plumbers and pipefitters working on residential and light commercial copper systems are the primary installers of this fitting.
This coupling is designed for straight-run connections in 1/16-inch copper tubing configurations. Its C x C end preparation accepts standard sweat solder joints, fitting into low-pressure water supply, refrigeration, or instrumentation line repairs where small-diameter copper tubing is used. The wrot copper construction provides consistent wall integrity and reliable solder flow at the joint interface.
Designed as an OEM-style replacement or new-installation fitting for small-bore copper tubing systems using standard C x C sweat solder joints.
Installation is performed by a licensed plumber or pipefitter. Shut off and depressurize the water supply line and allow all residual moisture to drain before soldering. Clean tube ends and fitting cups with emery cloth and apply flux per the solder manufacturer specifications before sweating the joint. Follow applicable IPC and local plumbing code requirements for potable water fittings.
