LOCTITE® 243™ is particularly suited for locking threaded fasteners of various equipment such as pumps, gearboxes, motors and vehicles,…

High precision

The thixotropic nature of LOCTITE® 243™ reduces the migration of liquid product after application to the substrate.

Suitable for a wide range of materials

Work on both active metals (e.g. brass, copper) and passive substrates such as stainless steel and plated surfaces.

Temperature tolerance

LOCTITE® 243™ can work continuously in the temperature ranges from -55ºC to +180ºC ( from -65.0 to360.0 °F )

Contamination tolerance

It tolerates minor surface contamination from various oils, such as cutting, lubrication, anti-corrosion and protection fluids.

LOCTITE® 243™ is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration.
