ICP Gas Valve Support Bracket for RGS121LDAB0AAAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket (part 1178238) secures the gas valve assembly inside the ICP / Tempstar / Heil RGS121LDAB0AAAA furnace, holding it in proper alignment with the manifold and burner train. A correctly mounted gas valve prevents stress on the gas line connections and keeps the valve positioned for safe, leak-free operation. Over years of thermal cycling and vibration, the original bracket can corrode, crack, or loosen — allowing the valve to shift, strain the pipe joints, or rattle. Installing a factory-correct replacement bracket restores rigid support and protects the gas train.
