The Lennox 99K39 Valve Expansion is a high-quality component designed for use in HVAC (Heating, Ventilation, and Air Conditioning) systems. This valve expansion tank is specifically engineered to work with Lennox's 99 series gas furnaces, ensuring a perfect fit and optimal performance.
The tank is made of durable materials, primarily corrosion-resistant copper and brass, ensuring its longevity and reliability in various weather conditions.

The tank is designed for easy installation, with a convenient threaded connection that fits directly onto the heating system's water supply line. Its compact size makes it suitable for spaces with limited clearance.
In summary, the Lennox 99K39 Valve Expansion tank is a reliable and durable component that plays a crucial role in maintaining the proper functioning of your Lennox 99 series gas furnace. Its high-quality materials, corrosion-resistant design, and convenient size make it an excellent choice for ensuring the longevity and efficiency of your HVAC system.
