ICP Gas Valve Support Bracket for RGS121SFBB0AAAA — OEM Mount | Ships Today

Overview

This is the genuine OEM gas valve support bracket (OEM 1178238) for the ICP / Heil / Tempstar RGS121SFBB0AAAA gas furnace. The bracket rigidly mounts the gas valve to the burner manifold assembly, holding it in alignment so the inlet and outlet connections stay leak-free and the valve cannot vibrate against adjacent components. A bent, cracked, or missing support bracket lets the gas valve flex under the weight of its piping, which can stress fittings, loosen connections, and create a gas leak hazard. Replacing a damaged bracket restores the factory-specified support for safe, reliable operation.
