Loctite ® 542™ Thread Sealant, Thread Sealing

Loctite ® 542 Thread Sealant, Thread Sealing is designed for the locking and sealing of metal pipes and fittings. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. The thixotropic nature of LOCTITE® 542 reduces the migration of liquid product after application to the substrate. Recommended for sealing fine threads of hydraulic and pneumatic connectors.

For metal, esp. hydraulic pipes.

Loctite Thread Sealants
Thread sealants prevent leakage of gases and liquids from pipe joints. All such joints are considered to be dynamic due to vibration, changing pressures or changing temperatures. Loctite anaerobic sealants cure to insoluble tough plastic thread fillers which prevent leakage regardless of the torque applied.
