The Greenstar Air Tube - Top Gasket (part no. 8711004278) is a replacement sealing gasket for Greenstar boiler air-tube assemblies, providing a tight seal at the air-tube top to help prevent air and combustion-gas leakage. Designed for service and parts inventory, it simplifies field maintenance for installers and wholesalers by restoring proper airflow pathways and supporting the integrity of the combustion enclosure without changing system operation.
