ICP Gas Valve Support Bracket for RGS121HDCA0AAA — OEM | Ships Today

Overview

This OEM gas valve support bracket (OEM 1178238) mounts and stabilizes the gas valve assembly in the ICP / Heil / Tempstar RGS121HDCA0AAA gas furnace. The bracket holds the gas valve in its correct position relative to the manifold and burners so the valve, gas line, and pilot/igniter geometry stay properly aligned and free of stress. A secure, undamaged bracket prevents the valve from sagging or vibrating, which protects the threaded gas connections from loosening and leaking. If the original bracket is bent, corroded, or cracked, the gas valve can shift, strain its piping, and create alignment or safety problems. This direct-fit replacement restores proper support for a safe, code-correct gas train. All gas work should be leak-tested and, where required, performed by a licensed technician.
