Loctite 542 is a medium strength, fast curing thread sealant designed for use with metal threads in pneumatic and hydraulic pipes and fittings. Loctite 542 cures in the absence of air between close fitting metal surfaces and prevents loosening and leakage caused by shock and vibration. Once applied to the part Loctite 542 will not run as it is thixotropic, meaning it maintains its viscosity in static conditions. Loctite 542 thread sealant can be applied on any size pipe fitting and can seal to the burst strength of most piping systems

A thread sealant is used to seal and secure plugs pipes and fittings and fill spaces between threaded metal parts.

A thread sealant, once it hardens or cures helps to prevent and stop leakages. Thread sealant also provides corrosion protection for the thread

• Fast curing
• Single component and quick and easy to apply
• Produces an instant low-pressure seal
• Provides resistance to vibration and shock loads
• Resistant to fuel, oil and hydraulic fluids

Loctite 542 hydraulic thread sealant is suitable for use in hydraulic and pneumatic installations, connections on machine tools, automotive vehicles, heavy plant equipment and small fittings
