Trane GKT2605 Gasket 320720-756 An 'OPN' message indicates anThe 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.
