Mueller Industries 15807 Copper 45 Street Elbow 1 in Ftg X C

Product Description

The MUELLER INDUSTRIES 15807 is a wrot copper 45-degree street elbow designed for sweat-solder copper piping systems. The street configuration uses a fitting-to-copper (FTG x C) end connection, allowing one end to insert directly into a standard copper fitting socket and the other to accept copper tube — eliminating the need for an additional coupling in close-quarters transitions. With a 1-inch fitting size and a 1-1/8-inch outside diameter, this elbow is a standard component in residential and light commercial plumbing and hydronic piping assemblies. Plumbers and pipefitters install this fitting during new construction and retrofit work where a 45-degree directional change is required.

This fitting is used in copper water supply, drain-waste-vent where copper is specified, and hydronic heating piping. The street elbow configuration is particularly useful in tight spaces where back-to-back fittings or offset runs are needed. The wrot copper construction — wrought and drawn from copper alloy — provides a consistent wall thickness and a clean interior bore that supports reliable solder joints. Package quantity is 2 pieces per unit.

Key Features

• 45-degree street elbow geometry for direction changes without an additional coupling
• FTG x C end connection — fitting end inserts into a standard socket; cup end accepts copper tube
• Wrot copper construction for consistent wall thickness and reliable sweat-solder joints
• 1-inch fitting size with 1-1/8-inch outside diameter
• Packaged as 2 pieces per unit

Compatibility

Designed as an OEM-style replacement and new-installation fitting for 1-inch copper piping systems using standard sweat-solder connections per ASTM and ASME B16.22 wrot copper fitting dimensions.

Installation Notes

Installation is performed by licensed plumbers or pipefitters following applicable IPC and local plumbing code requirements. Shut off and drain the water supply before cutting into any existing line. Clean tube ends and fitting sockets with emery cloth or fitting brush, apply flux, and solder with lead-free solder per code. Do not apply heat to the fitting while water or moisture remains inside the pipe.
