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 the tightest of spaces 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.
