Mueller Streamline CO45STLFTGC2 Copper 45 Degree Street Elbow 2 in

Product Description

The MUELLER STREAMLINE CO45STLFTGC2 is a 2-inch copper 45-degree street elbow with a fitting-to-copper (Ftg x C) end configuration. This fitting changes flow direction by 45 degrees within a copper piping system and is soldered in place using standard sweat-joint technique. The Ftg end accepts a standard copper tube outside diameter, allowing it to slip directly into another fitting socket without a separate coupling. Plumbers and pipefitters install this type of elbow in water supply, hydronic heating, and refrigeration line sets where moderate directional changes are required. Copper construction provides long-term corrosion resistance in both hot and cold water service.

This street elbow is suited for residential and light commercial plumbing and HVAC applications. The 45-degree angle is commonly used when routing supply or return lines around framing, mechanical equipment, or structural obstructions where a full 90-degree turn is not needed. The Ftg x C configuration is particularly useful when making back-to-back fitting connections without adding unnecessary pipe segments, keeping the installation compact and reducing the number of solder joints.

Key Features

• 45-degree directional change for moderate-angle routing in copper piping systems
• Street fitting (Ftg) inlet accepts standard copper tube OD for direct fitting-to-fitting connection
• Sweat (C) outlet connects to standard copper tube using soldered joint
• Copper construction resists corrosion in potable water, hydronic, and HVAC applications
• 2-inch size suited for main distribution lines in residential and light commercial systems

Compatibility

Designed as an OEM-style replacement and standard-use fitting compatible with 2-inch copper tube systems following ASTM and ASME sweat-fitting dimensional standards.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians using standard sweat-soldering tools including a torch, flux, and lead-free solder in compliance with local plumbing codes and IPC requirements. Shut off and drain the water supply completely before cutting into an existing line. Clean all mating surfaces with emery cloth or a fitting brush and apply flux evenly before heating. Never apply heat to a fitting that contains water, as steam pressure can compromise the solder joint.
