Part # Duo therm penguin gasket?

[HCR]

First good rain in three months I've had AS with resulting small puddle of water on floor. AC was not operating during rain.

Previously noticed small drip of water from AC after AC has been turned off. Doesn't drip when AC operating. Drip is small enough I can live w/it.

From what I've read here, need to replaced the gasket. Don't have AC manual from PO.

Is the gasket I need the 14 X 14 inch and is the part # 3310718006?

Thanks in advance.
