Description
The Trane GKT2605 is an OEM replacement collector box gasket designed to maintain a proper, airtight seal at the collector box assembly in compatible Trane furnace systems. A properly functioning collector box gasket is critical to safe and efficient furnace operation — preventing flue gas leaks, maintaining correct draft pressure, and protecting downstream components from combustion byproduct exposure.
Product Overview
This gasket serves as a precision-fit sealing component between the collector box and the heat exchanger or inducer assembly. Over time, gaskets can deteriorate due to heat cycling, condensation, and normal wear, leading to potential flue gas leakage or reduced system efficiency. Replacing a worn or damaged gasket with the genuine Trane GKT2605 restores the integrity of the combustion venting path and helps ensure safe, code-compliant operation.

Why Choose a Genuine OEM Gasket?
Using a genuine Trane replacement gasket ensures the correct material composition, thickness, and dimensions for a reliable seal. Aftermarket substitutes may not provide the same fit or durability, potentially leading to callbacks or safety concerns. The GKT2605 is the manufacturer-specified part for a reason — trust OEM quality for peace of mind on every installation.
