Kroil® Penetrant with Silicone (Formerly SiliKroil®) – 55 Gallon Drum

Kroil® Penetrant with Silicone (Formerly SiliKroil®) – 55 Gallon Drum

Industrial-scale penetrating oil with silicone for long-lasting lubrication and protection.

Kroil® Penetrant with Silicone—formerly SiliKroil®—pairs the legendary penetrating action of Kroil® with a silicone additive that leaves a thin, durable film for extended lubrication. It creeps into microscopic gaps to break the bond of rust, carbon, and corrosion, then protects against moisture and salt, making it ideal for coastal and high-humidity environments.

• Deep penetration: Frees rusted fasteners, shafts, pulleys, chains, valves, and slides.
• Silicone-enhanced: Leaves a long-lasting, low-friction film to prevent re-seizing.
• Corrosion control: Repels moisture and helps prevent future rust and oxidation.
• Industrial volume: 55-gallon drum supports fleet, plant, and hangar maintenance programs.
• Versatile application: Suitable for spray systems, wipe-on, or parts soaking stations.
• Compliance: Made in the USA; 50-state VOC compliant.

Choose the 55-gallon drum for continuous-use operations that demand reliable penetration and silicone-based lubrication. Formerly SiliKroil®, this updated branding delivers the same trusted performance—simplifying repairs, reducing downtime, and protecting equipment across industrial, automotive, marine, and aviation maintenance environments.
