ese washers are made of galvanized iron on one side with high hardness, corrosion protection and rust protection.
-The other side is neoprene EPDM, which has the properties of ageing resistance, resistance to high and low temperatures, acid and alkali resistance.
-Washers made of bonded neoprene (also known as sealing discs and damping discs) are special washers that ensure an airtight seal between the bolt or the screw and the hard surface.
-Waterproof sealing discs are smooth, hard and thick.
