Pre-coating

Pre-coating: an effective treatment for replacing liquid threadlockers and ensuring the sealing of assemblies

Pre-coating is a treatment method applied to the threaded or smooth part of a cylindrical component. It involves the application of a special product designed to be activated when the part is assembled, whether by screwing or press-fitting.
