ICP Gas Valve Support Bracket for RGS121HRCA0AAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) anchors the gas valve assembly to the manifold inside your ICP Tempstar Heil RGS121HRCA0AAA furnace. It holds the valve in rigid alignment so the manifold orifices, burners, and igniter stay correctly positioned and the gas train resists vibration and thermal stress. A cracked, corroded, or missing support bracket lets the valve shift, which can strain the gas line connection, misalign burner flame, or create a hazardous leak point. Replacing a failed bracket restores a safe, factory-spec gas valve mount.
