York S1-373-23784-003 Gasket Kit
The York S1-373-23784-003 Gasket Kit is a critical OEM replacement component engineered specifically for 21-inch upflow condensate pan assemblies in 90% efficiency residential furnaces. This kit ensures a pressure-tight seal between the heat exchanger cabinet and the drain pan, preventing hazardous combustion byproduct leakage and localized water damage. As a seasoned technician knows, a compromised condenser pan gasket can lead to secondary drain pan overflows and inefficient system pressure readings, making this precision-engineered furnace gasket replacement essential for maintaining UL-certified performance.
Designed for professional-grade HVAC system maintenance, the S1-373-23784-003 utilizes a high-density .9 material profile to withstand the corrosive environment produced by sustained condensation cycles. This kit includes all necessary seals to refresh the interface of the 21-inch cabinet, ensuring your condensate management system operates within the manufacturer's specified CFM and static pressure tolerances. When restoring York, Coleman, or Luxaire units, utilizing genuine York HVAC parts eliminates the risk of bypass air and ensures the longevity of the secondary heat exchanger housing.
Key Benefits:- Precision Fit: Specifically die-cut for 21-inch upflow chassis to ensure 100% surface contact and airtight sealing.
- OEM Durability: Constructed from professional-grade elastomers resistant to microbial growth and acetic acid common in furnace condensate.
- Enhanced Efficiency: Prevents air bypass around the condensate pan, maintaining optimal static pressure and blower motor performance.
- System Protection: Stops moisture from infiltrating the vestibule Area, protecting control boards and integrated components from corrosion.
- How do I know if the York S1-373-23784-003 is compatible with my furnace cabinet? This kit is specifically sized for upflow configurations with a 21-inch cabinet width; check your data plate or parts manual to confirm the B-width, C-width, or D-width sizing typical of York upflow units.
- Can this gasket be used in horizontal or downflow applications? This specific kit is optimized for upflow condensation drainage paths; while materials are similar, the geometry of the seals in the S1-373-23784-003 is task-specific for vertical upflow pan interfaces.
- Does this kit include more than one seal? Yes, the S1-373-23784-003 is a complete kit containing the necessary gaskets to fully reseal the condensate pan to the blower deck or cabinet floor.
