Nibco B460300 Cast Copper 90 Double Elbow 1x3/4x3/4

Product Description

The NIBCO B460300 is a cast copper 90-degree double elbow pressure fitting designed for copper pipe systems in residential and commercial plumbing applications. This three-port fitting connects a 1-inch run to two 3/4-inch outlets using sweat (C x C x C) end connections, making it a practical solution for branch takeoffs within a single elbow body. Cast copper construction provides reliable pressure ratings and long service life in potable water, hydronic heating, and general plumbing distribution systems. Licensed plumbers and pipefitters install this fitting as part of sweat-soldered copper piping assemblies.

This fitting is suited for residential and light commercial plumbing installations where a 90-degree directional change and simultaneous branch reduction are needed in a compact form. Its 1-inch by 3/4-inch by 3/4-inch configuration makes it appropriate for main-line-to-branch transitions in domestic hot and cold water distribution, radiant heating loops, and similar pressure piping systems. The C x C x C end connection style is compatible with standard sweat-solder copper pipe assembly methods.

Key Features

• Cast copper construction for durability in pressure piping systems
• 90-degree double elbow geometry allows directional change and dual branch in one fitting
• 1 inch x 3/4 inch x 3/4 inch sizing supports common main-to-branch transitions
• C x C x C end connections accept standard sweat-solder assembly
• Pressure fitting rating suitable for potable water and hydronic applications

Compatibility

Designed as an OEM-style sweat-solder pressure fitting for use with standard copper tube in residential and commercial plumbing systems where a 90-degree double elbow configuration with 1 inch by 3/4 inch by 3/4 inch sizing is required.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off and drain the water supply completely before cutting into any existing line. Clean and flux all pipe ends and fitting sockets thoroughly before applying heat to ensure a sound solder joint. Avoid overheating the fitting, as excessive heat can damage the copper and compromise joint integrity.
