ICP Gas Valve Support Bracket for RGS121HTCA0AAA — OEM Mounting Bracket | Ships Today

Overview

This OEM gas valve support bracket (OEM 1178238) secures the gas valve assembly in your ICP Tempstar/Heil RGS121HTCA0AAA gas furnace. The bracket holds the valve and its connected gas piping rigidly in place so that vibration, thermal cycling, and handling during service don't stress the threaded gas connections. A missing, bent, or corroded bracket can let the valve shift, putting strain on gas joints and risking leaks or misalignment with the manifold and burners. This factory bracket restores a secure, correctly positioned gas valve mount.
