ICP Gas Valve Support Bracket for RGS121HEAB0AAAA — OEM Mount | Ships Today

Overview

This is the genuine ICP gas valve support bracket (OEM 1178238) for the Tempstar/Heil RGS121HEAB0AAAA gas furnace. The bracket rigidly mounts and supports the gas valve within the burner compartment, holding it in proper alignment with the manifold and gas line so the valve does not flex, vibrate, or stress its threaded connections during operation. A correctly mounted gas valve is essential for safe, leak-free combustion. If the original bracket is bent, corroded, or was removed during a previous repair, the valve can sag and place strain on the gas piping — a potential leak point. This OEM bracket restores the factory mounting geometry exactly.
