Nibco B272900 Cast Copper Pipe Cross 2-1/2 in Cxcxc

Product Description

The NIBCO B272900 is a cast copper pipe cross fitting designed for use in pressure piping systems. It features a four-way C x C x C connection configuration, accepting standard copper tubing on all ends via a sweat-solder joint. The fitting measures 2-1/2 inches across all ports and weighs 2.96 pounds. It is manufactured from cast copper, providing the corrosion resistance and thermal conductivity required in potable water, heating, and general plumbing distribution systems. Licensed plumbers and pipefitters install this type of fitting where four lines must intersect at a single junction point in a copper piping network.

This fitting is suited for residential and light commercial plumbing, hydronic heating distribution, and mechanical room piping applications. The 2-1/2 inch size is common in main distribution headers and larger branch supply lines. It is installed wherever a copper cross configuration is required to route flow in four directions from a single connection point, eliminating the need for multiple separate fittings and reducing potential leak points in the assembly.

Key Features

• Cast copper construction provides excellent corrosion resistance and long service life in wet systems
• C x C x C x C end connections accept standard copper tubing for sweat-solder installation
• Pressure fitting style rated for standard plumbing and hydronic system operating pressures
• 2-1/2 inch fitting size suits main distribution and large branch piping applications
• Single-piece cast construction maintains consistent wall thickness at the junction

Compatibility

Designed as an OEM-style replacement and standard-use pressure fitting compatible with 2-1/2 inch copper tubing systems using sweat-solder C connections in residential and commercial plumbing and hydronic piping installations.

Installation Notes

Installation is performed by a licensed plumber or pipefitter following applicable IPC and local plumbing code requirements. Shut off and drain the water supply and relieve system pressure completely before cutting into an existing line. All four ports must be cleaned, fluxed, and properly soldered to achieve a watertight joint. Avoid overheating the fitting body during soldering, as excessive heat can damage the joint integrity of adjacent solder connections.
