Mueller Streamline CPL00875 Copper Coupling 1/8 C X C

Product Description

The MUELLER STREAMLINE CPL00875 is a wrot copper straight coupling designed for soldered 1/8-inch copper-to-copper connections. It features a rolled stop that ensures consistent pipe seating depth during assembly, improving joint integrity and reducing installation error. The fitting measures 0.6 inches in height and width and 1.38 inches in length. At 0.01 pounds, it is a lightweight, compact component suited for tight spaces in plumbing and HVAC refrigerant or water piping systems. It meets ASME and NSF standards, making it appropriate for potable water and mechanical system applications. Plumbers and HVAC technicians install this fitting in both new construction and retrofit work.

This coupling is used in residential and light commercial plumbing systems where a straight, in-line copper joint is required at the 1/8-inch pipe size. Its C x C solder-end configuration makes it compatible with standard copper tubing soldered with lead-free solder per applicable plumbing codes. It is a common component in small-diameter water supply lines, refrigeration piping, and instrument or control tubing runs where a reliable, leak-free joint is critical.

Key Features

• Wrot copper construction for reliable soldered joints and long service life
• Rolled stop ensures consistent pipe insertion depth and even solder flow
• 1/8-inch C x C straight configuration for in-line copper tube joining
• Meets ASME and NSF standards for mechanical and potable water applications
• Compact dimensions at 1.38 inches length and 0.6 inches width

Compatibility

Designed as an OEM-style replacement and standard fitting for 1/8-inch copper tube solder (C x C) connections in residential and commercial plumbing and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and ASME standards. Shut off and depressurize the system before cutting or joining any pipe. Clean and flux all mating surfaces thoroughly before soldering, and use lead-free solder where potable water applications are involved per applicable codes. Allow the joint to cool completely before restoring system pressure.
