LOCTITE 660 Retaining Compound is a high-strength, gap-filling anaerobic adhesive designed for retaining cylindrical parts, particularly where excessive clearance exists due to wear, machining errors, or loose fits. It is suitable for repairing worn housings, shafts, bearings, bushes, and other metal assemblies without the need to replace expensive components in many applications.

LOCTITELOCTITE 660 Retaining Compound is a high-strength, gap-filling anaerobic adhesive designed for retaining cylindrical parts, particularly where excessive clearance exists due to wear, machining errors, or loose fits. It is suitable for repairing worn housings, shafts, bearings, bushes, and other metal assemblies without the need to replace expensive components in many applications. 660 cures when confined between close-fitting metal surfaces in the absence of air. It creates a strong bond that helps prevent movement, loosening, and leakage between assembled components. Its gap-filling capability makes it particularly useful for worn or oversized metal parts where conventional retaining compounds may not provide adequate contact.
Key Features and Benefits
High-strength retention: Helps secure cylindrical metal components against movement.
Excellent gap filling: Designed for larger clearances in worn or poorly fitting assemblies.
Repair solution: Helps restore the functionality of worn shafts, bearing seats, and housings.
Reliable metal bonding: Suitable for various metal substrates, subject to product compatibility.
Reduced component replacement: Can help extend the service life of machinery parts.
Industrial applications: Useful for maintenance, repair, and assembly operations.
