Thermoseal ML-N562
High performance multi-layer sheet
KLINGER 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°).
