Mueller Streamline CPL00884 Copper Coupling 1-3/8 Cxc

Product Description

The MUELLER STREAMLINE CPL00884 is a wrot copper rolled-stop coupling designed for sweat-solder connections in copper piping systems. The rolled stop is a formed internal shoulder that controls insertion depth, ensuring consistent, correctly seated joints every time. At 0.22 pounds and measuring 2.25 inches in length, this fitting is sized for 1-3/8 inch nominal copper tube on both ends with a C x C (copper by copper) connection configuration. It is a standard production fitting used daily by licensed plumbers and HVAC technicians on refrigerant line sets, hydronic systems, and potable water distribution. Compliance with ASME and NSF standards makes it suitable for systems where material certification is required by code or inspection.

This coupling is used wherever two lengths of 1-3/8 inch copper tube must be joined inline. Common applications include refrigeration and air conditioning line set runs, chilled water piping, and general plumbing rough-in. The C x C end connections require a solder-sweat joint on both sides, making installation straightforward for any tradesperson equipped for copper work. It fits residential and light commercial applications and is appropriate for both new construction and retrofit repairs where an existing copper run must be extended or spliced.

Key Features

• Rolled internal stop controls insertion depth for consistent, repeatable solder joints
• Wrot copper construction provides high pressure and temperature tolerance typical of production copper fittings
• C x C ends accept standard sweat-solder connections on both sides
• 1-3/8 x 1-3/8 inch connection size suits refrigeration line sets and hydronic piping
• ASME and NSF compliant for use in systems requiring certified materials
• Compact form factor at 2.25 inches in length and 0.22 pounds

Compatibility

Designed as an OEM-style sweat coupling for 1-3/8 inch outside-diameter copper tube in C x C configurations across residential and light commercial plumbing, HVAC, and refrigeration piping systems.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and ASME guidelines. Isolate and depressurize the system and drain standing water from the pipe before cutting and fitting. Clean and flux both tube ends and the fitting sockets thoroughly before applying heat to ensure a sound solder joint. Allow the joint to cool completely before restoring system pressure.
