York S1-373-23784-002 Gasket Kit
The York S1-373-23784-002 Gasket Kit is a critical OEM maintenance component designed for high-efficiency 90% AFUE furnace systems. Specifically engineered for 17.5-inch upflow configurations, this condensate pan gasket kit ensures a gastight and airtight seal between the heat exchanger assembly and the drainage system. Utilizing genuine Johnson Controls/York replacement parts prevents the loss of static pressure and blocks the leakage of acidic condensate, which can lead to premature corrosion of the cabinet and base pan. This kit is built to withstand the thermal cycling and chemical exposure common in condensing furnace environments, providing a durable HVAC sealing solution that maintains the integrity of the secondary heat exchanger interface.
- OEM Compatibility: Exact fit for 17.5-inch width upflow furnace cabinets, ensuring no-gap alignment.
- System Efficiency: Prevents bypass airflow, maintaining the designed static pressure across the condensing coil.
- Corrosion Resistance: High-grade gasket material specifically formulated to resist the corrosive properties of HVAC condensate.
- Leak Prevention: Eliminates water damage risks to the furnace control board and blower motor by securing the condensate collector pan.
- Precision Tolerance: Manufactured to the original engineering specifications for a first-time fix without field modifications.
Common Technical Questions
Is this kit compatible with horizontal or downflow furnace orientations?
This specific part number is designed for 17.5-inch upflow models. Always verify the cabinet width and unit orientation against the technical guide to ensure the gasket profile matches the condensate pan flange.
Does this kit include the adhesive or mounting hardware?
The kit typically includes the precut gaskets required for the seal. Technicians should inspect existing hardware and surfaces for corrosion before installation to ensure a flat, clean mating surface.
How do I confirm if my leaking furnace needs a new gasket kit?
If you observe water pooling near the secondary heat exchanger or evidence of "rust tracking" from the collector box, the York S1-373-23784-002 is the standard solution for restoring the factory seal.
