PERMATEX® Medium Strength Threadlocker BLUE Gel is a medium strength anaerobic threadlocking gel conveniently packaged in a new Gel Squeeze™ applicator. The product, like its liquid counterpart, is a single component, anaerobic gel that cures when confined in the absence of air between close fitting metal surfaces, ideal for all 6 mm to 25 mm (1/4" to 1") diameter threaded assemblies. Excellent chemical resistance and temperature resistance range of -65 degree Fahrenheit to +300 degree Fahrenheit (-54 degree Celsius to +149 degree Celsius). The assembly is easily removable with hand tools for servicing requirements. NSF Nonfood Components Program Listed (P1) (135871).

Directions For Use:

For Assembly

  • Clean all threads (bolt and hole) with a cleaning solvent such as Permatex® Brake and Parts Cleaner and allow to dry.
  • Remove the translucent protective cap by pulling off at an angle.
  • Remove cap and squeeze 1/8 to 1/4" (3 mm to 6 mm) of material beyond tip.
  • Apply threadlocker to the engagement area of the male fitting (usually the leading 5 to 6 threads).
  • Assemble parts and tighten to recommended torque.
  • If unused gel contacts metal threads, do not retract threadlocker back into the tube. Wipe off with a clean towel.
  • Replace protective cap.

For Cleanup

  • Residual liquid films and/or fillets outside the joint are readily soluble in Permatex® Brake and Parts Cleaner.
  • Cured product can be removed with a combination of soaking in Permatex® Gasket Remover and mechanical abrasion such as a wire brush.

For Disassembly

  • Remove with standard hand tools.
  • In the rare instance where hand tools do not work, because of excessive engagement length, apply localized heat to nut or bolt to approximately 450 degree Fahrenheit (232 degree Celsius). Disassemble while hot.

For Reassembly

  • Remove loose product from nut and bolt following cleanup procedure above.
  • Apply Surface Prep™ activator to all threads, regardless of metal type and allow to dry.
  • Apply threadlocker gel as above.
  • Assemble and tighten as usual.
