ICP Gas Valve Support Bracket for RGS121STCB0AAA — OEM 1178238 | Ships Today

Overview

This OEM gas valve support bracket (part #1178238) secures the gas valve assembly inside the ICP/Tempstar/Heil RGS121STCB0AAA furnace. The bracket holds the valve in proper alignment with the manifold and burner assembly, preventing stress on the gas line connections and ensuring the valve seats correctly. A bent, corroded, or missing bracket can allow the gas valve to shift, causing manifold misalignment, gas line strain, and potential leaks. This is the exact factory component, not a universal substitute.
