I had purchased this about 10 Months ago and had noticed that the newer models had the gasket to seal the lid, located on the lid. Mine was on the body of the cooler.

I contacted Lifetime to purchase the other gasket and they said they would send me the other gasket at no charge. They did and with some silicon sealant, it works great. In Florida, it gets extremely hot and humid, so dual gaskets is keeping everything a bit cooler!

Thank you for the excellent Customer Service!
