Kroil® Penetrant with Silicone (Formerly SiliKroil®) – 10oz to 15 Gallon
Kroil® Penetrant with Silicone (Formerly SiliKroil®) – 10oz to 15 Gallon
Powerful penetrating oil with added silicone for superior lubrication and protection.
Kroil® Penetrant with Silicone, formerly known as SiliKroil®, combines the proven penetrating action of Kroil® with the long-lasting lubricity of silicone. This advanced formula creeps into the tightest clearances to break the bond of rust, corrosion, and carbon buildup while leaving behind a thin silicone film that prevents future seizing and provides lasting protection against moisture, salt, and oxidation.
- Extra lubrication: Silicone additive enhances long-term performance and rust protection.
- Deep penetration: Reaches microscopic gaps to loosen seized or corroded parts.
- Safe on metal: Non-corrosive and non-staining formula that will not attack metal surfaces.
- Moisture resistant: Repels water, salt, and humidity for dependable corrosion control.
- Versatile use: Ideal for bearings, valves, pulleys, hinges, chains, and gate mechanisms.
- Available sizes: 10oz, 16.5oz, 1 Gallon, 5 Gallon, and 15 Gallon containers.
Engineered for professional maintenance, Kroil® Penetrant with Silicone is the choice for technicians who demand high-performance rust penetration and lubrication. It works wherever metal parts seize, stick, or corrode—especially in high-humidity or coastal environments. Formerly sold as SiliKroil®, it’s the same trusted formula with updated branding and 50-state VOC compliance.


Technical Specifications
- Sizes: 10oz, 16.5oz, 1 Gallon, 5 Gallon, 15 Gallon.
