ICP Gas Valve Support Bracket for RGS121LRBB0AAAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP Tempstar/Heil RGS121LRBB0AAAA gas furnace. The bracket secures and positions the gas valve assembly inside the burner compartment, holding it in correct alignment with the manifold and burner orifices. A properly mounted gas valve is critical for safe, leak-free combustion — a missing, bent, or corroded bracket can let the valve shift, stress the gas line, and cause manifold misalignment. Replace the bracket whenever you service the valve or find it cracked, rusted, or deformed.
