ICP Gas Valve Support Bracket for RGS120HFAA0AGAA — OEM Mount | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) mounts and stabilizes the gas valve assembly inside the ICP, Tempstar, and Heil RGS120HFAA0AGAA furnace. The bracket holds the valve in its factory position so the inlet and manifold piping stay properly aligned and free of stress. A bent, corroded, or missing bracket lets the valve and gas line flex with every cycle, which can loosen pipe joints, strain the manifold, and create leak risk. Installing the correct OEM bracket restores secure, vibration-free mounting and keeps the gas train aligned to spec.
