Mueller Streamline W 03012 45 Deg Elbow 1/4 in Wrot Copper

Product Description

The MUELLER STREAMLINE W 03012 is a 45-degree wrot copper elbow fitting designed for solder-joint (sweat) connections in pressurized supply piping systems. It features a C x C (copper by copper) end configuration with a 1/4-inch nominal size, making it suited for small-diameter branch lines and tight-space routing where a 45-degree directional change is required. Wrot copper construction delivers consistent wall thickness and reliable joint integrity under normal operating pressures. This fitting is installed by licensed plumbers and HVAC technicians working on residential and light commercial water supply, refrigeration, and hydronic piping systems.

This elbow is a standard solder-joint fitting used wherever a 45-degree offset or directional change is needed in a 1/4-inch copper line. Typical applications include refrigerant piping, potable water supply lines, compressed air lines, and hydronic heating circuits. The 1/4-inch end size is common in refrigeration and ice-maker supply line work. Domestically manufactured, it meets the dimensional standards expected for sweat-fit copper fittings in both new construction and retrofit installations.

Key Features

• 45-degree angle provides a gradual directional change to reduce turbulence in the line
• C x C end configuration accepts standard copper tubing for soldered sweat connections
• 1/4-inch nominal size suited for small-diameter refrigeration, supply, and ice-maker lines
• Wrot copper construction ensures consistent dimensional tolerances and strong solder joints
• Domestically manufactured to standard solder-joint fitting dimensions

Compatibility

Designed as an OEM-style replacement or new-installation solder-joint fitting for 1/4-inch copper tubing in pressurized supply and refrigeration piping systems.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician in accordance with applicable plumbing codes, including IPC and local amendments. Shut off and depressurize the line before cutting and fitting. Clean tubing ends and fitting cups thoroughly with emery cloth and flux before applying solder; follow safe soldering practices and use lead-free solder for potable water applications. Avoid overheating the fitting, as excessive heat can compromise joint integrity.
