These neoprene flat washers provide a tight moisture barrier to seal out liquids and gas and also help cushion the nut or bolt head. It is the same washer used in a bonded sealing washer. The package size designates the inner diameter of the washer. Used in applications with nuts and bolts or screws where moisture prevention is a concern.
