ICP Gas Valve Support Bracket for RGS121LDBB0AAAA — OEM Mounting Bracket | Ships Today

Overview

This is the genuine OEM gas valve support bracket (OEM #1178238) for the ICP/Heil/Tempstar RGS121LDBB0AAAA gas furnace. The bracket holds the gas valve in proper alignment with the burner manifold and inlet piping, preventing strain on the gas connections and keeping the valve steady against vibration. A bent, corroded, or missing support bracket can let the gas valve sag and stress the threaded joints — a potential gas-leak and reliability concern. Replacing the bracket restores correct, secure gas-valve mounting.
