ICP Gas Valve Support Bracket for RGS121SEAA0AAAA — OEM 1178238 | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) is the mounting bracket that secures the gas valve assembly inside the ICP / Tempstar / Heil RGS121SEAA0AAAA gas furnace. It holds the valve in the correct position relative to the manifold and burners so that gas line connections stay aligned and stress-free. A bent, corroded, or missing bracket lets the gas valve shift, which can strain the manifold threads, stress the inlet/outlet piping, and create vibration that loosens fittings over time. Replacing a damaged bracket restores proper valve support during a valve replacement or after corrosion damage.
