ICP Gas Valve Support Bracket for RGS120LDAB0AGAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP/Tempstar/Heil RGS120LDAB0AGAA gas furnace. This bracket rigidly mounts and supports the gas valve and manifold assembly inside the furnace, holding the valve in proper alignment with the burner inlet and preventing stress on the gas piping connections. A bent, corroded, or missing support bracket allows the gas valve to shift, which can strain the pipe joints, misalign the manifold to the burners, and create vibration or potential leak points. Replacing a damaged bracket restores secure, leak-free mounting of the valve assembly.
