Trane GKT2605 Gasket
The Trane GKT2605 is a high-precision Collector Box Gasket designed specifically for sealing the interface between the secondary heat exchanger and the collector box in Trane condensing furnaces. As any veteran tech knows, a degraded gasket in the flue assembly is a safety risk; this OEM replacement ensures a gas-tight seal to contain combustion byproducts like carbon monoxide while maintaining the negative pressure required for the draft inducer. Engineered from high-performance elastomers, the GKT2605 gasket provides superior thermal resistance and durability against the corrosive effects of acidic condensate typical in high-efficiency 90% AFUE and above units.
Replacing this HVAC collector box seal during routine maintenance or inducer service is critical to preventing air bypass and ensuring the furnace flue system operates at peak efficiency. This part is a direct Trane OEM replacement part, ensuring factory-standard fitment and compression rates that aftermarket alternatives often fail to replicate. Whether you are addressing a leak in a residential gas furnace or performing a complete secondary heat exchanger teardown, using the correct Trane furnace gasket is essential for a professional, leak-proof call.
Key Benefits:- Ensures a gas-tight collector box seal to prevent carbon monoxide leakage into the cabinet.
- Constructed from high-grade materials to withstand high temperatures and acidic furnace condensate.
- Maintains proper static pressure within the venting system for reliable inducer motor operation.
- Designed for a precise fit on specific Trane and American Standard condensing furnace models.
- Critical component for restoring system efficiency and preventing premature component failure due to air infiltration.
How do I know if my Trane collector box gasket is failing?
Technicians should look for signs of "white" mineral deposits or moisture tracking around the perimeter of the collector box. If you see condensate leaking onto the blower deck, the gasket has likely lost its compression set or has been compromised by heat cycles.
Can I use high-temp silicone instead of the GKT2605 gasket?
While some techs use RTV in emergencies, the GKT2605 is designed with a specific thickness and density to provide a uniform seal across the entire mating surface. Using the OEM gasket avoids the mess and cure time of silicone while ensuring the flue system remains within factory specifications.
Which furnace models use the GKT2605?
This gasket is commonly found in Trane S-Series and older high-efficiency condensing units. Always verify your specific model and serial number to ensure compatibility with the collector box and secondary heat exchanger assembly.
