Tough General Use Lubricant Works Fast To Dissolve Rust

Monolex® is a fast-acting, surfacewetting formula that works as a light lubricating oil as well as penetrating lubricant. The tough film created by Monolex is far more effective than ordinary oils. Its excellent penetrating ability helps it work its way through layers of rust, gum, resins, varnish and dirt, dissolving or washing them away and quickly loosening “frozen” components – even those that are hard to reach. Monolex also contains a water-displacing agent that drives out moisture, allowing it to retard corrosion, even in saltwater applications.

Lubrication Engineers operates under an ISO 9001 Certified Quality System.

Proprietary Additive

N/A LE’s proprietary additives are used exclusively in LE lubricants. Monolex Penetrating Oil & Lubricant contains Monolec.

Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
