ICP Gas Valve Support Bracket for RGS121LTCB0AAA — OEM Mounting Hardware | Ships Today

Overview

This OEM gas valve support bracket (part #1178238) holds the gas valve in its correct position inside the ICP/Tempstar/Heil RGS121LTCB0AAA gas furnace. The bracket anchors the valve body to the burner assembly so the gas piping and manifold stay properly aligned and free of stress. A bent, corroded, or missing bracket lets the valve shift, which can strain the inlet and manifold connections and create the risk of a gas leak or misaligned burner flame. This factory bracket restores the exact mounting geometry so the valve, manifold, and burners sit in their designed positions. It is a common item to replace during a gas valve swap or after corrosion damage in the burner box.
