Permatex® medium strength threadlocker blue gel is a medium strength anaerobic threadlocking gel conveniently packaged in a new Gel Twist™ or Gel Squeeze™ applicator.

OEM specified. Gel formula provides liquid-reliability without drips, globs, mess or waste. Eliminates need for stocking expensive lock nuts and lock washers. Locks and seals while preventing parts loosening due to vibration. Protects threads from corrosion. Removable with hand tools for easy disassembly.
