Where to buy

LOCTITE® 641

Features and Benefits

This medium-strength retaining compound is designed for bonding cylindrical fitting parts, particularly where regular servicing is needed.
When you’re working with parts that need regular dismantling – retention of bearings on shafts and in housings, for example – try LOCTITE® 641. This medium-strength anaerobic retaining compound cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration.
