Carrier 336818-403 Rear Cell Panel Gasket

The Carrier 336818-403 Rear Cell Panel Gasket is about 14.25” L, 0.5” W, 0. 001” T, being an HVAC exclusive part presumably for Carrier air conditioners and furnaces. Regard it as a gasket needed for the back panel of the unit to be watertight. This gasket provides close contact between the back cell panel and the cabinet so that there is no allowance for air to pass through. In this way, the Rear Cell Panel Gasket effectively seals this connection and thus contributes to the better system efficiency. It prevents conditioned air from escaping from the machine in addition to protecting the interior of the machine from dust, dirt and moisture.
