Mueller Industries 15837 Copper 90 Sr Street Elbow 3/4 in

Product Description

The MUELLER INDUSTRIES 15837 is a wrot copper 90-degree short radius street elbow designed for sweat-solder copper piping systems. It transitions from a fitting-size male end (FTG) to a standard cup-end female connection (C), allowing direct in-line connections without an additional coupling. The short radius geometry keeps the fitting compact in tight spaces, making it a practical choice where clearance is limited. At 3/4 inch fitting size with a 7/8 inch outside diameter, this elbow is a standard component for licensed plumbers working on domestic water supply, hydronic heating, and HVAC condensate or refrigerant piping applications.

This street elbow is suited for residential and light commercial plumbing and mechanical systems. The FTG x C end configuration allows one end to insert directly into a fitting socket, eliminating the need for a separate coupling when making a directional change. Typical applications include water supply branch lines, boiler piping, and copper drain or vent transitions where a 90-degree turn with minimal center-line offset is required. Package quantity is 5 pieces per pack.

Key Features

• Wrot copper construction provides high-pressure and high-temperature performance in sweat-solder assemblies
• 90-degree short radius design minimizes center-line offset for tight-clearance installations
• FTG x C end connection allows direct socket insertion without an extra coupling
• 3/4 inch fitting size with 7/8 inch outside diameter meets standard copper tube sizing
• Sold in packs of 5, with a minimum order quantity of 1 pack

Compatibility

Designed as an OEM-style replacement and standard-use fitting compatible with 3/4 inch wrot copper sweat-solder piping systems per ASTM B16.22 standard copper fitting dimensions.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply and drain the line before cutting or soldering. Clean all mating surfaces with emery cloth and apply flux before soldering; use lead-free solder where required by code for potable water systems. Allow joints to cool fully before restoring pressure and inspecting for leaks.
