Additional Product Information
Overview
LOCTITE 660 is a high-strength anaerobic retaining compound designed to restore worn cylindrical metal parts and secure assemblies with large bond gaps. Widely used across aviation maintenance, repair, and overhaul (MRO), it cures in the absence of air between close-fitting metal surfaces to prevent loosening, vibration damage, and leakage. Aviation teams rely on it to extend component life, reduce downtime, and enable fast, reliable AOG repairs without immediate part replacement.Key Technical Specs for LOCTITE 660
