Low Strength Threadlocker Purple (6ml).

Permatex Threadlocker Purple is a low-strength threadlocker specifically designed for small fasteners under 1/4" (6mm) that may require occasional adjustment or disassembly. It prevents loosening due to vibration, seals threaded connections to prevent leaks, and is non-corrosive, protecting the threads from damage. A key benefit of Threadlocker Purple is that it allows for easy disassembly with hand tools.
