Mueller Industries 15864 Cast Copper 90 Elbow 1/2 in Cxf

Product Description

The MUELLER INDUSTRIES 15864 is a cast copper 90-degree elbow fitting designed to change flow direction in copper piping systems. It features a 1/2 inch by 1/2 inch end configuration with a C x F (sweat by female) connection, allowing direct soldering to copper tubing on the sweat end while accepting a male threaded connection on the female end. Cast copper construction delivers consistent wall thickness and reliable joint integrity. Licensed plumbers and HVAC technicians install this fitting in both new construction and retrofit applications where a precise 90-degree turn is required in a copper supply or hydronic line.

This elbow is suited for residential and light commercial plumbing and HVAC hydronic systems. The C x F configuration makes it a practical choice when transitioning from a soldered copper run to a threaded component such as a valve, fixture supply, or equipment port. It is commonly found in domestic water supply lines, radiant heating loops, and refrigeration piping where a 90-degree direction change and a threaded termination point are needed at the same fitting.

Key Features

• 90-degree elbow geometry for in-line direction changes in copper piping runs
• Cast copper material for consistent dimensional accuracy and strong solder joints
• C x F end connection combines a sweat inlet with a female threaded outlet in a single fitting
• 1/2 inch by 1/2 inch fitting size suits common residential water and HVAC piping
• Sold in a package quantity of 5, with a minimum order quantity of 1

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1/2 inch copper piping systems requiring a C x F 90-degree elbow connection.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off and depressurize the water or fluid system before cutting into any existing line. The sweat end requires proper flux application, clean-cut tubing, and a torch-and-solder process per applicable IPC and IFGC guidelines. Ensure the female threaded port is mated with compatible male threads and appropriate thread sealant to prevent leaks at the transition point.
