Device for sealed attachment

摘要

The assembly (10) has a washer (11) assembled on a female fastener that is designed as a fastening nut (12) or a collar. The washer comprises a cylindrical skirt (13) rigidly connected to an outer periphery of an annular base (15). The base is partially covered with a layer (21) of a viscous composition utilized for forming a liquid-tight seal through polymerization. The fastener is assembled onto the washer by adhering to the layer of the composition that comprises liquid polysulfide and reagent capable of releasing oxygen i.e. manganese dioxide. The viscous composition comprises liquid polysulfide and reagent capable of releasing oxygen i.e. manganese dioxide. An independent claim is also included for a method for assembling a leak-proof assembly for a fastening system.
