Sioux Chief 672X0990 9-port 3/4 in Pex Closed Copper Manifold

Product Description

The SIOUX CHIEF 672X0990 is a 9-port, 3/4-inch PEX closed manifold constructed with copper, designed for residential and light commercial hydronic or domestic water distribution systems. This manifold serves as a central distribution point, splitting a single supply line into multiple individual branch circuits. Each of the nine ports accepts 3/4-inch PEX tubing, and the closed-end design means no additional end cap is required at installation. Licensed plumbers and PEX system installers use this component when running home-run or parallel distribution layouts.

This manifold is well suited for radiant floor heating systems, domestic hot and cold water distribution, and potable water supply applications where individual zone control or circuit isolation is needed. The 9-branch configuration supports medium to larger residential builds or multi-zone installations where a single manifold location handles an entire floor or system level. Its copper construction is compatible with standard PEX installation practices used in new construction and retrofit projects.

Key Features

• 9 individual ports provide high-capacity branch distribution from a single supply point
• 3/4-inch PEX connections on all branch ports for direct PEX tubing integration
• Closed-end manifold design eliminates the need for a separate end cap fitting
• Copper construction offers durability and compatibility with potable water systems
• Home-run layout capable, supporting individual circuit shutoff when paired with isolation valves

Compatibility

Designed as an OEM-style replacement or new-installation component for 3/4-inch PEX closed-end copper manifold applications in residential and light commercial plumbing and hydronic distribution systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the main water supply and depressurize the system before connecting or disconnecting any manifold ports. Use appropriate PEX crimp, clamp, or expansion tooling rated for 3/4-inch connections as specified by the fitting system in use. Support the manifold per manufacturer and code requirements to prevent stress on branch connections.
