ICP Gas Valve Support Bracket for RGS121LTCA0AAA — OEM 1178238 | Ships Today

Overview

This OEM gas valve support bracket 1178238 mounts and stabilizes the gas valve assembly inside the ICP / Tempstar / Heil RGS121LTCA0AAA furnace. It holds the valve in the correct position relative to the manifold and burners so the gas piping isn't stressed and the valve stays rigid through years of thermal cycling and vibration. A bent, corroded, or missing bracket lets the valve and manifold flex, which can stress threaded connections and create the conditions for a gas leak. This OEM bracket restores the factory mounting geometry.
