ICP Gas Valve Support Bracket for RGS120LDAB0AAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part #1178238) for the ICP/Heil/Tempstar RGS120LDAB0AAA furnace. Note: this is the mounting bracket only — the gas valve itself is sold separately. The bracket holds the gas valve in its correct position relative to the manifold and burners, preventing strain on the gas piping and keeping the valve aligned for proper combustion. A bent, cracked, or corroded bracket can allow the valve and manifold to shift, stressing pipe joints and affecting burner alignment.
