Choosing the Correct SONLOK Product

SONLOK grades are not interchangeable. Threadlocker strength determines whether a threaded assembly is intended to remain serviceable or become effectively permanent; gasket, retaining and thread-seal grades perform different jobs. Match the grade to the metal assembly, thread size, required serviceability and operating conditions.

Application Guidance

Clean and prepare parts as required by the current Parson instructions. Anaerobic cure depends on confinement between compatible metal surfaces, and cure speed varies with material, gap and temperature. Use the correct primer or activator when required for inactive surfaces or production speed.
