ICP Gas Valve Support Bracket for RGS121LTBB0AAAA — OEM 1178238 | Ships Today

Overview

This genuine OEM gas valve support bracket, part number 1178238, mounts and stabilizes the gas valve and manifold assembly inside the ICP / Tempstar / Heil RGS121LTBB0AAAA gas furnace. The bracket holds the valve in correct alignment with the burner manifold so the gas orifices stay properly indexed to the burners and so vibration does not stress the gas piping or the valve body. A corroded, bent, or missing support bracket allows the valve and manifold to sag, which can misalign the flame, strain the inlet union, and create a potential gas-leak point.
