Mueller Industries BDNA-15821 Wrot Copper 90 Elbow 3/4x1/2

Product Description

The MUELLER INDUSTRIES BDNA-15821 is a wrot copper 90-degree elbow fitting designed to change flow direction in copper piping systems. It connects two copper pipes at a right angle using sweat (solder) connections on both ends, designated as C x C. The fitting measures 3/4 inch on one end and 1/2 inch on the other, making it a reducing elbow suited for transitioning between pipe sizes within a single run. Wrot copper construction provides reliable pressure ratings and corrosion resistance appropriate for potable water, hydronic heating, and refrigeration line applications. Licensed plumbers and HVAC technicians are the primary installers of this fitting.

This reducing elbow is used in residential and light commercial plumbing and HVAC systems wherever a 90-degree directional change is needed between a 3/4-inch and 1/2-inch copper line. Common applications include domestic hot and cold water distribution, baseboard hydronic heating loops, and refrigerant line sets. The C x C end connections require standard soldering with lead-free solder per applicable plumbing codes. It is sold individually with a minimum order quantity of 5 units.

Key Features

• Wrot copper construction for high-integrity solder joints and long service life
• Reducing configuration: 3/4 inch x 1/2 inch for in-line size transitions
• C x C (sweat) end connections on both ends
• 90-degree elbow geometry for right-angle directional changes
• Outside diameters of 7/8 inch and 5/8 inch on respective ends
• UNSPSC Code 40175305 for procurement classification

Compatibility

Designed as an OEM-style replacement and standard-use fitting compatible with 3/4-inch and 1/2-inch copper tubing systems using sweat (solder) end connections in plumbing and HVAC applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and IAPMO or IPC standards. Shut off and depressurize the water or refrigerant system fully before cutting into existing lines. Clean and flux all mating surfaces before soldering, and use lead-free solder where required by code for potable water applications. Allow the joint to cool completely before restoring system pressure.
