Nibco B064250 Cast Copper 90 Elbow 3/4x1 C X F

Product Description

The NIBCO B064250 is a cast copper 90-degree elbow fitting designed to connect copper tubing at a right angle in residential and commercial plumbing and hydronic systems. It features a sweat-solder Cup by Female (C x F) end connection in a 3/4 inch by 1 inch size, allowing a transition between two different nominal pipe sizes. Manufactured from cast copper to ASTM B584 and ISO standards, this pressure fitting delivers reliable, leak-resistant joints when properly soldered. Licensed plumbers and pipefitters install this type of fitting during new construction, remodel work, and system repairs.

This elbow is suited for potable water supply lines, hydronic heating distribution piping, and general-purpose copper pressure piping in both residential and light commercial applications. The C x F configuration is commonly used where a copper tubing run terminates into or transitions from a female-threaded component, such as a valve body or pump port. The 3/4 inch by 1 inch size accommodates common mixed-diameter branch and main line connections found in domestic plumbing systems.

Key Features

• 90-degree elbow geometry for right-angle directional changes in copper piping runs
• Cast copper construction meets ASTM B584 and ISO standards for pressure service
• Cup by Female (C x F) end connections for sweat-solder to female-threaded transition
• 3/4 inch by 1 inch sizing supports mixed-diameter piping configurations
• Pressure fitting style rated for standard potable water and hydronic system service pressures

Compatibility

Designed as an OEM-style pressure fitting replacement or new-installation component for copper tube systems conforming to standard nominal sizing in residential and commercial plumbing and hydronic heating applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off water supply and fully drain the affected piping section before cutting or fitting work begins. Tube ends and fitting sockets must be cleaned and fluxed before soldering to achieve a sound, leak-free joint. Do not apply heat to the fitting while it is under pressure or while flammable materials are in the immediate work area.
