ICP Gas Valve Support Bracket for RGS121STAA0AAAA — OEM Mount | Ships Today

Overview

This is the genuine OEM ICP gas valve support bracket, part number 1178238, for the RGS121STAA0AAAA gas furnace. The bracket mechanically anchors the gas valve and its manifold/piping so the assembly stays rigid against vibration, thermal cycling, and the torque applied during pipe connections. A secure bracket protects the valve body and gas joints from stress that can lead to leaks or cracked fittings over time. If your original bracket is bent, corroded, or was removed during a prior repair, replacing it restores the factory mounting and keeps the gas train properly aligned. This is a mechanical mounting component only — it does not include the gas valve itself.

2. Access — Remove the burner compartment service panel.
3. Document — Photograph the gas valve, bracket, and manifold orientation before loosening anything.
4. Remove — Support the gas valve, then remove the fasteners holding the old bracket. Avoid stressing the gas piping.
5. Install — Position the new 1178238 bracket, refasten the valve assembly, and verify the manifold alignment.
6. Test — Restore gas, leak-check all joints with soap solution, restore power, and run a heat cycle.
