ICP Gas Valve Support Bracket for RGS120SEAB0AGAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket, ICP part number 1178238, for the RGS120SEAB0AGAA gas furnace. The bracket fixes the gas valve in its correct position within the burner compartment so the manifold, valve, and burner orifices stay in precise alignment. Proper support prevents stress on the manifold pipe threads and keeps the valve from sagging or vibrating loose over years of cycling. A bent, corroded, or missing bracket can allow the gas valve to shift, which risks misaligned burners, manifold leaks, and unsafe combustion. Replacing the bracket with the factory part restores the correct geometry and keeps the gas train rigid and serviceable.
