Mueller Industries BDNA-15734 Copper Coupling 5/8 in Cxc

Product Description

The MUELLER INDUSTRIES BDNA-15734 is a wrot copper pipe coupling designed for sweat-soldered copper tubing connections in residential and commercial plumbing and HVAC refrigerant piping systems. The fitting accepts 5/8 inch tubing with a copper-to-copper (C x C) end connection on both sides, creating a straight inline joint. Wrot copper construction provides consistent wall thickness, high pressure tolerance, and reliable solder bonding. This coupling is a standard field fitting for licensed plumbers and HVAC technicians working with copper tubing runs.

This coupling is suited for potable water supply lines, hydronic heating loops, refrigerant line sets, and general copper pipe repair or extension work. The C x C configuration requires standard sweat-soldering technique with appropriate flux and lead-free solder per local plumbing code requirements. It is appropriate for both new installation and repair applications wherever a straight inline copper connection is needed.

Key Features

• Wrot copper construction for uniform wall thickness and strong solder joints
• 5/8 inch fitting size with C x C (copper-to-copper) sweat connections on both ends
• 3/4 inch outside diameter
• Straight inline coupling for joining or repairing copper tubing runs
• Compatible with lead-free solder for potable water applications

Compatibility

Designed as an OEM-style replacement and standard field fitting for 5/8 inch copper tubing systems using sweat-soldered C x C connections in plumbing and HVAC applications.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician. Shut off and depressurize the water or refrigerant system before cutting into any existing line. Clean and flux both the tubing ends and the fitting socket before soldering. All work should conform to applicable local plumbing codes and ASTM standards for lead-free solder in potable water systems.
