Henkel LOCTITE-672 (50-ml-Btl)

Additional Product Information

Overview

LOCTITE 672 is a medium-strength anaerobic retaining compound designed for bonding cylindrical metal assemblies where secure retention and future disassembly are required. Widely used in aviation maintenance and MRO environments, it cures in the absence of air between close-fitting metal parts to prevent loosening, fretting, and leakage caused by vibration and shock. Maintenance teams rely on it for dependable bearing retention and serviceable assemblies in time-critical AOG situations.
