ICP Gas Valve Support Bracket for RGS121LSAA0AAAA — OEM Mounting Bracket | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part 1178238) for the ICP Tempstar Heil RGS121LSAA0AAAA gas furnace. The bracket rigidly mounts the gas valve assembly to the furnace burner box, holding the valve and its manifold in correct alignment with the burners. Proper bracket support prevents stress on the gas line connections, reduces vibration, and keeps the valve from shifting during operation. A bent, corroded, or missing bracket can allow the gas valve to sag, stressing the manifold joint and creating a potential gas-leak point — so a sound bracket is a small but safety-critical part of the burner assembly.
