ICP Gas Valve Support Bracket for RGS121LRBA0AAAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part number 1178238) for the ICP Tempstar/Heil RGS121LRBA0AAAA gas furnace. The bracket mounts and stabilizes the gas valve inside the burner compartment, keeping it aligned with the manifold and burner assembly. Correct valve mounting is essential for safe combustion — a cracked, corroded, or missing bracket lets the valve shift, strains the gas line, and can throw off manifold alignment. Replace the bracket whenever you service the gas valve or find the existing hardware rusted, bent, or broken.
