ICP Gas Valve Support Bracket for RGS121LRCA0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP / Tempstar / Heil RGS121LRCA0AAA gas furnace. The bracket secures the gas valve to the burner assembly and maintains correct alignment between the valve outlet, the manifold, and the burner orifices. Proper bracket support prevents vibration, gas-line stress, and manifold misalignment that can cause poor flame quality or nuisance lockouts. If the original bracket is cracked, corroded, or was damaged during a previous valve replacement, installing a new factory bracket restores correct, code-compliant valve mounting.
