Kroil® Original Penetrating Oil – 55 Gallon Drum

Kroil® Original Penetrating Oil – 55 Gallon Drum

The original “Oil That Creeps,” now in industrial bulk.

Kroil® Original Penetrating Oil in a 55-gallon drum delivers proven, fast-acting penetration for plant maintenance, fleet service, and heavy industrial repair. The formula creeps into one-millionth-inch spaces to break the bond of rust, carbon, and corrosion—freeing seized fasteners and components—then helps clean, lubricate, displace moisture, and resist future rust.

• Deep penetration: Loosens rusted nuts, bolts, studs, pulleys, couplings, and fittings.
• Cleans & protects: Dissolves gum, dried grease, and carbon; displaces moisture to deter corrosion.
• Industrial efficiency: Bulk 55-gallon supply supports shop-wide maintenance programs and soak tanks.
• Trusted performance: The original Kroil® formula technicians have relied on since 1939.
• Compliance: 50-state VOC compliant; made in the USA.
• NSF Listed H2: Nonfood Compounds Program, Reg. #165745 (bulk/gallon formats).

Choose Kroil® Original when precision parts and stubborn fasteners need reliable, non-destructive release. Apply directly or use in controlled dispensing and bath applications to speed teardown, reduce rework, and keep equipment online.
