NYSEAL® is a patented, pre-applied permanently fused sealing element.

Developed in answer to a customer's need for a highly-durable fastener sealing element that could perform under high pressure, and was resistant to a wide variety of chemicals, NYSEAL® eliminates the need and cost of secondary application during the assembly process.

Green-colored NYSEAL creates a gasket-type seal, preventing leakage of fluids and gases under pressures up to 500 psi. 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 under the bearing surface of the head and countersink/counterbore. With the seal in place, galvanic corrosion between dissimilar metals such as aluminim and steel is prevented.
