ICP Gas Valve Support Bracket for RGS121HRBB0AAAA — OEM 1178238 | Ships Today

Overview

This is the genuine OEM gas valve support bracket (part #1178238) for the ICP / Heil / Tempstar RGS121HRBB0AAAA gas furnace. The bracket mechanically anchors the gas valve to the furnace burner assembly, holding it in correct alignment with the manifold so the gas-to-burner connection stays leak-free and vibration does not stress the valve body or fittings. This is a structural support component, not the gas valve itself. A bent, corroded, or missing bracket can allow the valve to sag, strain the manifold joints, and create the conditions for a gas leak.
