LOCTITE® 510 High Temperature Gasket Sealant :


  • Anaerobic curing: Forms a strong seal when confined between close-fitting metal surfaces in the absence of air.
  • High temperature resistance: Withstands temperatures up to 315°C (599°F) continuously.
  • Chemical resistance: Resists oils, fuels, coolants, and most chemicals.
  • Low pressure seal: Creates an instant seal for immediate leak protection.
  • Medium strength: Easy to disassemble but provides a reliable seal.
  • Pink paste: Easy to see for accurate application.


  • Sealing rigid metal flanges: Engine valve covers, oil pans, gearboxes, differentials, etc.
  • Filling small gaps: Between machined metal surfaces.
  • Gasket eliminator: Can replace pre-cut gaskets in some applications.
