Mueller Streamline CPL00133 Copper Coupling 1/8 C X C

Product Description

The MUELLER STREAMLINE CPL00133 is a wrot copper no-stop coupling designed for joining 1/8-inch copper tubing in sweat-solder applications. The no-stop design allows the fitting to be pushed through the tube end without obstruction, making it useful for in-line repairs where a standard coupling stop would prevent insertion. At 0.6 inches tall, 0.6 inches wide, and 1.38 inches in length, this is a compact fitting suited for tight spaces. It connects copper-to-copper (C x C) and meets ASME and NSF standards. Plumbers and HVAC technicians install this fitting using standard soldering practices.

This coupling is used in residential and light commercial plumbing and refrigeration tubing systems where 1/8-inch copper lines are joined or repaired. The no-stop configuration is particularly valuable when replacing a damaged section of tubing mid-run, as the fitting slides freely over the tube end before being positioned and soldered. It is appropriate for both new construction and service work on small-diameter copper systems.

Key Features

• No-stop design allows full insertion over tube end for in-line repairs
• Wrot copper construction for reliable sweat-solder joints
• C x C connection type for copper-to-copper applications
• Compact size: 0.6 inches wide by 1.38 inches in length
• Meets ASME and NSF standards for plumbing applications

Compatibility

Designed as an OEM-style replacement fitting for 1/8-inch copper tubing systems using C x C sweat connections in residential and commercial plumbing or HVAC applications.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians trained in copper sweat-solder work. Shut off the water or refrigerant supply and depressurize the line before fitting installation. Clean and flux both tube ends before soldering, and follow applicable codes including the IPC and IFGC for plumbing and gas-line copper work. Do not use this fitting on pressurized systems without verifying the system pressure rating against applicable standards.
