ICP Gas Valve Support Bracket for RGS121LEAA0AAAA – OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part #1178238) for the ICP / Heil / Tempstar RGS121LEAA0AAAA gas furnace. The bracket secures the gas valve assembly to the burner manifold, keeping the valve, inlet piping, and burner orifices in proper factory alignment during operation and service. A corroded, cracked, or missing bracket allows the gas valve to sag or vibrate, stressing the gas line connection, misaligning the burners, and creating a potential leak path. Installing a sound bracket restores secure, spec-correct mounting.
