Since the expressions "parts" and "parts and accessories" do not apply to "joints, washers or the like of any material" whether or not they are identifiable as for the goods of Section XVII (i.e. vehicles, aircraft, vessels and associated transport equipment) by virtue of Legal Note 2(a) to that Section, gaskets for use in transportation vehicles are classified according to their constituent material or in heading 84.84. For instance, agglomerated cork automotive transmission gasket would be classified as an article of agglomerated cork in subheading 4504.90 as HS Code for cork_gaskets. You may refer to HS Code for Gaskets to see all types of gaskets classified according to their constituent material.
