Agglomerated Cork Washers for Plumbing Fixtures
Ring-shaped washers fabricated from agglomerated cork, used in faucets and valves for compression sealing in plumbing applications. They qualify under HTS 4504.10.47.00 as 'other' washers of agglomerated cork, typically in disk or cylindrical form with a central hole. The material's compressibility makes it ideal for non-corrosive gaskets.
