ICP Gas Valve Support Bracket for RGS120HDAA0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS120HDAA0AAA gas furnace. The bracket secures the gas valve assembly to the burner manifold, holding it in the correct alignment so the valve, manifold, and burner orifices stay properly seated. A cracked, corroded, or missing bracket lets the gas valve sag or vibrate, which can stress the gas line connection, throw off burner alignment, and create noise or a gas-tightness concern. Replacing a damaged bracket with the exact-fit OEM part restores the factory mounting geometry.
