Nibco B064050 Cast Copper 90 Elbow 1/2x1/4 C X F

Product Description

The NIBCO B064050 is a cast copper 90 degree elbow fitting designed for pressure piping systems in residential and light commercial plumbing applications. It provides a 90-degree directional change in copper tubing runs, connecting a 1/2-inch copper sweat end to a 1/4-inch female threaded end. The C x F configuration means one side accepts a soldered cup connection while the other accepts a male-threaded pipe. Cast from copper alloy per ASTM B584 and ISO standards, this fitting delivers reliable performance in water distribution and mechanical systems where a transition from sweat to threaded connection is required.

This elbow is suited for residential plumbing, HVAC refrigerant line ancillary connections, and light commercial water distribution where a 90-degree turn and a sweat-to-thread transition are needed in the same fitting. The 1/2-inch cup inlet and 1/4-inch female thread outlet make it a practical choice for ice maker supply lines, humidifier feeds, and similar small-bore branch connections. Licensed plumbers and HVAC technicians are the primary installers of this type of fitting.

Key Features

Compatibility

Designed as an OEM-style pressure fitting for use in copper tube plumbing systems requiring a 90-degree direction change with a sweat-to-female-thread transition at 1/2-inch by 1/4-inch sizing.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and the IPC. Shut off the water supply and depressurize the line before soldering. The cup end requires proper cleaning, flux application, and lead-free solder per current code requirements before applying heat. The female threaded outlet should be joined with appropriate thread sealant or tape rated for the intended service fluid.
