Fastener Seals

Parker´s fastener seals are composite sealing washers, consisting of a metallic carrier and a vulcanized elastomer sealing lip. They provide a static sealing function on flanges or threaded connections, and consistently assure ideal compression conditions between the housing components to prevent the destruction of the sealing lip.
