Kroil® Penetrant with Graphite (Formerly Penephite®) – 13 oz to 15 Gallon

Kroil® Penetrant with Graphite (Formerly Penephite®) – 13.5oz to 15 Gallon

High-performance penetrating oil with added graphite for lasting lubrication.

Kroil® Penetrant with Graphite, formerly known as Penephite®, combines the legendary penetrating power of Kroil® with the dry-film lubricating strength of graphite. This advanced formula creeps into the smallest gaps and corrosion layers to loosen frozen fasteners, bolts, and fittings—while leaving behind a protective graphite film that withstands temperatures up to 700°F (371°C).

• Penetrates deeply: Breaks through rust, carbon, and corrosion to free seized components.
• Graphite-enhanced lubrication: Leaves a high-temperature film that protects against friction and galling.
• Versatile use: Ideal for aviation, automotive, industrial, and marine maintenance.
• Corrosion protection: Repels moisture and prevents future rust formation.
• Temperature resistant: Maintains lubrication up to 700°F (371°C).
• Available sizes: 13.5oz Aerosol, 1 Gallon, 5 Gallon, and 15 Gallon containers.

Engineered for professional-grade maintenance, Kroil® Penetrant with Graphite excels in high-stress environments where other lubricants fail. From aviation maintenance hangars to industrial facilities, it simplifies repairs, reduces downtime, and provides long-lasting lubrication under extreme heat and pressure. Formerly Penephite®—same trusted formula, new name.
