Orange, anaerobic-curing gasketing product ideal for sealing close fitting metal flanges.
LOCTITE® 549 is an orange, medium strength, slow curing, thixotropic methacrylate gasketing product. It cures in the absence of air at room temperature when confined within close fitting metal parts to seal rigid metal faces and flanges. The viscosity is 20,000 mPas and service temperature -55°C to 150°C (-67°F to 302°F).
  • Thixotropic for ease of application
  • Slow curing
  • Provides instant seal to low pressures immediately after assembly
  • 1-part: no mixing required
  • Medium viscosity
