Loctite 641 Retaining Compound Medium Strength

Loctite 641 is a medium strength retaining compound designed for the bonding of cylindrical fitting parts, particularly when disassembly is required for servicing operations. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage due to shock and vibration. Ideal for parts that need subsequent dismantling, i.e. retention of bearings on shafts and in housings.
