I have and old koolerator with 6 faucets and the rear gasket had deteriorated over time. These new gaskets did the job. My only complaint is that MoreFlavor could have mailed them in an envelope for under a buck but I had to pay MOREshipping of $8 only to receive a massive box with packing for a couple tiny plastic bags with my gaskets weighing less than an ounce. Not much common sense here but hey when the customer is paying outrageous shipping for such a tiny item whatever.
