Thermoseal ML-N562

High performance multi-layer sheet

Thermoseal's Multi-Layer Technology materials provide both exceptional interfacial and interstitial sealability. Conformable outer layers prevent leakage between the gasket and flanges and a strong high-density core provides structural support while preventing leakage through the gasket.

ML-N562 is a synthetic fiber and nitrile butadiene gasket material designed for difficult sealing applications with very low flange pressure or very rough surface finishes. It combines a Multi-Layer Technology structure for exceptional low flange pressure sealability and exceptional torque retention together with a more compressible core. ML-N562 provides heat and chemical resistance in coolant, lubricant, and hot air applications.

Typical applications include automotive, marine, and small engine applications with intermittent operating temperatures up to 500°F (260C°).

The ability of a gasket to make and maintain a seal depends not only on the style and quality of the gasket material, but also on medium being sealed, the flange design, the amount of pressure applied to the gasket by the bolts and how the gasket is assembled onto the flanges and tightened. These factors are beyond the manufacturer's control.
