Mueller Industries W 01034 Copper Coupling 3/4 in

Product Description

The MUELLER INDUSTRIES W 01034 is a wrot copper pipe coupling designed for sweat-soldered copper piping systems. It accepts 3/4 inch copper tubing on both ends using a C x C (copper-to-copper) end connection and a solder joint assembly method. The outside diameter measures 7/8 inch. Wrot copper construction delivers reliable pressure performance and corrosion resistance in potable water, hydronic, and HVAC refrigerant piping applications. This coupling is a standard straight fitting with no stop, allowing pipe sections to be joined end-to-end. Licensed plumbers and HVAC technicians install this fitting as part of new construction and repair work.

This coupling is suited for residential and light commercial plumbing and mechanical systems where copper sweat fittings are specified. Typical applications include domestic hot and cold water distribution, hydronic heating loops, and refrigeration line sets. It is sold individually but must be ordered in multiples of 5 per manufacturer minimum order quantity. The fitting meets multiple ASME dimensional and performance standards as well as NSF 61G for potable water contact.

Key Features

• Wrot copper construction for strength and corrosion resistance in wet service environments
• C x C end connection accepts standard 3/4 inch copper tubing on both ends
• Solder joint assembly compatible with standard lead-free solder and flux
• Outside diameter of 7/8 inch fits standard copper tube size tooling
• Meets ASME B16.22 and NSF 61G for use in potable water systems

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 3/4 inch copper pipe systems using sweat solder connections in plumbing and mechanical piping applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IAPMO or IPC requirements. Shut off and drain the water supply or depressurize the system before cutting or soldering. Clean tube ends and fitting sockets thoroughly with emery cloth and apply flux before heating. Use only lead-free solder where required by code for potable water applications.
