Nibco 90405600 Wrot Copper Companion Flange 3 in

Product Description

The NIBCO 90405600 is a 3-inch wrot copper sweat companion flange designed for use in plumbing and piping systems that require a secure, leak-resistant flanged connection. The fitting is constructed from wrot copper and includes a 150-pound-rated steel ring with a 7.5-inch outer diameter. It is installed by licensed plumbers and pipefitters working on commercial and residential piping systems where flanged terminations are required at valves, pumps, or equipment connections.

This companion flange is suited for sweat-connection installations on 3-inch copper piping. It pairs with standard 150-class flanged components, making it a practical choice for hydronic heating systems, chilled water lines, domestic water supply, and similar applications that demand a copper-to-flange transition at equipment access points or service locations.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter. Shut off the water supply and fully depressurize and drain the system before cutting into any existing line. Use standard soldering practice per applicable plumbing codes such as the IPC before attaching the flange ring. Ensure bolt torque on the mating flange is applied evenly in a cross pattern to achieve a proper seal.
