NYSEAL® creates a gasket-type seal, preventing leakage of fluids and gases under pressure. The coating is permanently fused on the bearing surface of the fastener. As the screw is seated to its final position against the mating part, the NYSEAL® element compresses slightly and fills the void between the bearing surface of the head and the counter sink/counter bore.
