LOCTITE 641 is a medium-strength anaerobic adhesive designed for bonding cylindrical fitting parts such as bearings, sleeves, bushings, and shafts. It is ideal for applications where future disassembly is required, providing a secure hold while still allowing easy removal with standard tools.

This retaining compound cures in the absence of air between closely fitted metal surfaces, forming a strong, vibration-resistant bond. It helps restore worn parts, prevent fretting corrosion, and improve the overall reliability of mechanical assemblies.
