Loctite 660 Retaining Compound


Loctite 660 Retaining Compound

Loctite 660 is designed for the bonding of cylindrical fitting parts without the need for re-machining, particularly where bond gaps are larger such as with worn parts. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.


  • Used for repairing worn coaxial parts without re-machining.
  • Prevents loosening: It fills all gaps between the cylindrical components and cures into a hard thermoset plastic. This unitizes the assembly and prevents loosening and leakage from shock and vibration.
