Trane GKT2604 Gasket

As a seasoned tech, you know that maintaining a true negative pressure seal in a furnace is non-negotiable for system safety and performance. The Trane GKT2604 Gasket is a critical OEM component specifically engineered to seal the interface between the collector box and the heat exchanger partition. In high-efficiency condensing furnaces, the collector box gasket is vital for managing flue gas condensate and preventing air bypass that can trip pressure switches or lead to premature inducer motor failure. This Trane GKT2604 Collector Box Gasket features high-temp resilient construction capable of withstanding the corrosive environment of flue condensate and the thermal cycling typical of residential gas furnaces.

Measured at approximately 9" x 16" with a 0.2" thickness, this replacement HVAC gasket ensures a leak-proof flue assembly. Utilizing a genuine Trane furnace part like the GKT2604 maintains the integrity of the combustion path, preventing carbon monoxide infiltration and ensuring the secondary heat exchanger operates at peak thermal efficiency. Whether you are performing a mid-season repair for a leaky furnace collector box or a full flue assembly overhaul, this Trane OEM gasket provides the precise fit required to avoid "no-heat" service calls caused by poor seals.

• Ensures a precision collector box seal to maintain essential negative pressure for pressure switch closure.
• Constructed from heavy-duty, condensate-resistant material to prevent heat exchanger bypass and air leaks.
• Direct Trane GKT2604 replacement for seamless integration with existing flue assembly mounting holes.
• Critical for preventing moisture and corrosive flue gases from damaging the furnace chassis and burner components.
• Designed for high-efficiency gas furnaces to support optimal airflow and combustion safety.

Is the Trane GKT2604 compatible with my specific furnace model?
This gasket is primarily utilized in Trane and American Standard high-efficiency condensing furnaces. Check the service manual or the "Box, Flue Collector" diagram in your technical guide to confirm the GKT2604 is the specified SKU for your serial number.

What are the signs that a collector box gasket needs to be replaced?
Technicians should look for signs of rust or water staining near the inducer, frequent pressure switch faults, or visible deterioration of the existing seal during annual heat exchanger inspections.

Can I use high-temp RTV silicone instead of this OEM gasket?
While RTV can sometimes serve as a temporary fix for hairline cracks in the box itself, it is not a substitute for the structural seal provided by the Trane GKT2604 Gasket, which is engineered for the specific tolerances of the partition interface.
