ICP Gas Valve Support Bracket for RGS121HEBB0AAAA — OEM Mount 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238, BRACKET SUPPORT GAS VALVE) for the ICP / Tempstar / Heil RGS121HEBB0AAAA gas furnace. The bracket holds the gas valve and burner manifold in rigid alignment so the burners fire correctly and the gas piping is not stressed. A bent, corroded, or missing support bracket lets the valve and manifold sag or vibrate, which can cause misaligned flames, noisy operation, or strain on the gas connections. This is the factory-correct mounting hardware, sized specifically for this furnace's valve and manifold assembly.
