Royal Purple Max-Tuff® synthetic assembly lubricant is an ultra-tough, synthetic lubricant designed for use in reassembling repaired equipment.  Royal purple Max Tuff lubricants utilizes unique, synthetic molecules that adhere tenaciously to metal surfaces to create a formidable, load-bearing physical barrier between surfaces.  This minimizes the possibility of boundary conditions (metal-to-metal contact) while providing excellent protection to both ferrous and nonferrous metals against rust and corrosion.  Synslide® Additive Technology Makes the Difference!
