Mueller Industries 15808 Copper 45 Street Elbow 1-1/4 in

Product Description

The MUELLER INDUSTRIES 15808 is a wrot copper 45-degree street elbow designed for copper plumbing and hydronic piping systems. The fitting size is 1-1/4 inches with a FTG x C (fitting by copper) end connection, allowing it to be soldered directly into a socket-end fitting on one side while accepting a standard copper tube on the other. Wrot copper construction provides consistent wall thickness and a smooth interior bore, making it well-suited for pressure and fluid-handling applications. This elbow is typically installed by licensed plumbers working on residential or light commercial water supply, drain, and heating systems.

This 45-degree street elbow is used where a moderate directional change is needed in a copper piping run. The FTG x C configuration eliminates the need for an additional coupling when transitioning from a fitting hub to a tube end, saving space in tight installations. Typical applications include water supply lines, radiant heating loops, and general plumbing rough-in work in residential and commercial buildings.

Key Features

• Wrot copper construction for consistent wall thickness and pressure integrity
• 45-degree angle for moderate directional offsets in piping runs
• FTG x C end connection allows direct insertion into a fitting socket on one end
• 1-1/4 inch fitting size with 1-3/8 inch outside diameter
• Sweat-solder joining method compatible with standard copper tube and fittings

Compatibility

Designed as an OEM-style replacement and general-use fitting for 1-1/4 inch copper piping systems using standard sweat-solder connections.

Installation Notes

Installation is performed by a licensed plumber using standard sweat-soldering tools including a torch, flux, and lead-free solder in accordance with local plumbing codes and ASTM standards. Shut off and depressurize the water supply and allow all pipes to cool completely before cutting or joining. Ensure pipe ends and fitting sockets are cleaned and fluxed properly before applying heat. Follow all applicable IPC and local jurisdiction requirements for potable water applications.
