ICP Gas Valve Support Bracket for RGS121LRAA0AAAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket (part #1178238) is the factory mounting bracket for the ICP / Heil / Tempstar RGS121LRAA0AAAA gas furnace. The bracket holds the gas valve securely in position within the manifold and burner assembly, maintaining correct alignment between the valve, gas line, and burners. A solid, properly mounted gas valve is critical for safe operation — a loose or vibrating valve can stress the gas line connections, cause leaks, or throw off burner alignment. This bracket is commonly needed when servicing or replacing the gas valve, or when the original bracket is corroded, bent, or damaged.
