Lennox 89M58 Gas Valve

The Lennox 89M58 Gas Valve is a critical OEM component designed for high-performance gas regulation in residential and commercial heating systems. As a 3/4 inch gas valve, this unit is engineered to manage the precise flow of fuel, ensuring stable combustion across a wide range of legacy Lennox, Allied, Armstrong, and Ducane furnaces. This specific Lennox 89M58 replacement is physically and functionally identical to the 89M5801, providing a direct drop-in solution for technicians addressing manifold pressure inconsistencies or total valve failure. Included with this assembly is a liquid propane conversion kit, making it a versatile LP gas valve kit for field-conversions where natural gas is unavailable. By maintaining the correct furnace gas valve 24V signal response, this component preserves the original efficiency ratings of the equipment. Whether you are performing a routine service or a complete system overhaul, utilizing genuine OEM Lennox HVAC parts ensures exact port alignment and electrical terminal compatibility without the need for field modifications.
