D-5263NS is a general purpose, low temperature, water displacing preservative oil used as a lubricant and rust preventive for general Aircraft applications including cables. This product was designed to provide maximum life to all aircraft cables. It can also be used with excellent results on small guns, machine guns and precision machine parts.
