Vibra-Tite VC-5 exhibits similar performance to Vibra-Tite VC-3 except it contains a base solvent of Methyl Propyl Ketone. VC-5 is one of the most versatile threadlockers available on the market. Unlike traditional liquid lockers which cure to form a hard bond, VC-5 is a blend of resins designed to remain flexible and absorb vibration. This unique difference makes VC-5 coated fasteners truly adjustable, removable, and reusable.
