Nibco 3992335147 Companion Flange 2.5 in Cts Lead Free

Product Description

The NIBCO 3992335147 is a 2.5-inch companion flange designed for use with CTS (Copper Tube Size) piping systems. Manufactured under the NIBCO 672 series, this lead-free flange provides a secure, leak-resistant connection point where a pipe or valve assembly meets a flanged fitting or equipment port. It is commonly installed by licensed plumbers in both residential and light commercial applications where lead-free compliance is required by code. The companion flange mates with a corresponding flange to form a bolted joint, allowing for easy disassembly during maintenance or equipment replacement.

This flange is suited for CTS piping installations where a removable, flanged connection is needed. Typical applications include connecting water service lines, boiler system piping, and plumbing distribution runs to pumps, valves, or other flanged equipment. The lead-free construction makes it appropriate for potable water systems subject to state and federal lead-free mandates, including installations governed by NSF and Safe Drinking Water Act requirements.

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 the water supply and depressurize the line before beginning any flange work. Verify gasket seating and bolt torque patterns follow standard flanged joint practices to prevent leaks. Confirm all components in the assembly are rated lead-free before installing on potable water lines.
