Mueller Industries W 03012 Copper 45 Elbow 1/4 in C X C

Product Description

The MUELLER INDUSTRIES W 03012 is a wrot copper 45-degree elbow fitting designed for sweat-soldered copper piping systems. It measures 1/4 inch in fitting size with a copper-to-copper (C x C) end connection and is joined using a standard solder joint method. Wrot copper construction provides a dense, work-hardened grain structure that offers consistent wall thickness and reliable pressure integrity. This fitting is used by licensed plumbers and HVAC technicians in both new construction and retrofit applications where a 45-degree change in pipe direction is required. The fitting weighs approximately 0.011 pounds.

This elbow is suited for residential and light commercial plumbing, hydronic heating, refrigeration piping, and HVAC line sets where 1/4-inch copper tubing is specified. The C x C solder joint configuration requires standard tube preparation, flux application, and lead-free solder per applicable codes. It is appropriate for use in potable water systems that require NSF 61G compliance, as well as in pressure piping governed by ASME dimensional standards.

Key Features

• Wrot copper construction for consistent wall thickness and pressure integrity
• 45-degree elbow geometry for low-resistance directional changes in copper piping
• C x C solder joint ends compatible with standard sweat-soldering tools and technique
• Outside diameter of 3/8 inch per ASME B16.22 dimensional standards
• NSF 61G listed for use in potable water systems
• Meets multiple ASME standards including B16.15, B16.18, B16.22, B16.24, and B16.50

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1/4-inch copper tube in residential and commercial plumbing and HVAC systems where C x C solder joint connections are specified.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with local plumbing codes, the International Plumbing Code (IPC), and ASME standards. Shut off and depressurize the water or refrigerant system before cutting or joining any piping. Tube ends must be cut square, deburred, cleaned, and fluxed before soldering. Use lead-free solder for all potable water applications as required by applicable codes.
