Mueller Industries BDNA-15816 Copper 90 Elbow 1/4 X 1/4 C X C

Product Description

The MUELLER INDUSTRIES BDNA-15816 is a wrot copper 90-degree elbow fitting designed for sweat-connection copper piping systems. With a 1/4-inch by 1/4-inch end size and a cup-by-cup (C x C) connection type, this elbow redirects flow at a right angle in tight-clearance installations. Wrot copper construction provides the ductility and leak-resistance that plumbing and HVAC professionals rely on in both high-pressure and high-temperature service conditions. The outside diameter measures 3/8 inch on both ends. This fitting is a standard component in refrigeration line sets, small-diameter plumbing supply lines, and HVAC coil piping assemblies where a sharp directional change is required.

This elbow is suited for residential and light commercial applications involving 1/4-inch copper tubing. Typical install scenarios include refrigeration branch circuits, condensate or supply connections on HVAC equipment, and small-bore plumbing where a 90-degree turn is needed in a confined space. The C x C end connections are intended for soldered or brazed joints per standard trade practice. This fitting ships individually but carries a minimum order quantity of 10 units.

Key Features

• Wrot copper construction for superior ductility and pressure integrity
• 90-degree elbow geometry for right-angle directional changes in piping runs
• C x C (cup-by-cup) ends accept standard sweat solder or braze joints
• 1/4-inch x 1/4-inch fitting size suits small-bore refrigeration and plumbing lines
• 3/8-inch outside diameter on both ends for consistent fitment

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/4-inch nominal wrot copper piping systems using cup-by-cup sweat connections.

Installation Notes

Installation should be performed by a licensed plumber, refrigeration mechanic, or HVAC technician familiar with copper sweat or braze procedures. Shut off and recover any refrigerant or depressurize the water supply line before cutting into existing piping. Clean and deburr tube ends and the fitting cup before applying flux and soldering or brazing per applicable codes, including ASME B16.22 and the International Plumbing Code. Do not overtorque or force-fit the connection, as wrot copper cups are sized for close tolerances.
