Trutite 313 Thread Lock is a medium-strength anaerobic thread locking compound designed for the instant assembly of threaded fasteners and metal fittings. This high-performance liquid thread lock helps prevent loosening and leaks caused by vibration, shock and movement in mechanical assemblies.
The anaerobic thread locking formula cures in the absence of oxygen when confined between metal threads. As the air between mating metal fittings is eliminated, the liquid begins to cure and forms a durable bond that secures the assembly. This process creates a strong and reliable sealant that helps maintain the integrity of threaded fasteners while still allowing disassembly with standard hand tools for maintenance or replacement purposes.
Trutite 313 Thread Lock is effective on steel, brass, stainless steel, aluminium and other metal components. Its medium-strength design provides dependable thread locking performance while allowing future servicing when required. Suitable for a wide range of industrial, engineering, automotive and maintenance applications, it helps prevent loosening and leaks from vibrations while improving the reliability of threaded connections.
