2-inch flanged heater gasket

This gasket fits Waterway and Gecko 2-inch heaters, among others. It has a smooth face on one side and a ribbed face on the other. If your hot tub heater is leaking at the unions, chances are you need to replace these gaskets. We recommend that you replace both gaskets at the same time.
