Kroil Penetrant with Silicone (formerly SiliKroil) has been engineered to loosen frozen metal parts and provide extra lubrication for long-lasting protection. The addition of silicone to the legendary Kroil formula results in superior penetration, lubrication and rust prevention. This high solvency oil first penetrates into spaces as tight as one-millionth of an inch to break the bond of rust, and then provides lubrication at the first molecular level, subsequently freeing virtually any metal part. Kroil Penetrant with Silicone is designed for use on frozen bearings, slides, gate valves, hinges, chains, and more. Excellent for use in coastal areas or anyplace where exposure to salt and weather is a factor.

A large airplane factory reported having trouble with air-driven rivet guns, which slowed down production. The maintenance team applied Kroil Penetrant with Silicone (formerly SiliKroil) to the air-driven equipment, and voilà, the production line was flying again.
Trailer hitches don’t usually get much love. They’re often left out in the elements for long periods of time. When hitches lock up or get rusty, spray them with Kroil Penetrant with Silicone to loosen and lubricate for lasting use.
Apply a top-coat of Kroil Penetrant with Silicone for additional cleaning and long-lasting lubrication, after loosening rusted chain mechanisms with Kroil Original Penetrant.
