Kroil: Professional-Grade Solutions for Tough Maintenance Jobs
Kroil: Professional-Grade Solutions for Tough Maintenance Jobs
Industrial maintenance often involves more than simply lubricating a moving part. Rusted fasteners, seized components, built-up deposits, difficult-to-clean surfaces and extreme operating temperatures can all create challenges during maintenance and repair.
Kroil is a long-established industrial maintenance brand known for its penetrating oils and products designed to help solve these types of difficult jobs. Founded in 1939, Kroil began with a focus on developing professional-grade penetrants and has since expanded its product range into several areas of maintenance and protection.
What Is Kroil?
Kroil was established in Chicago in 1939 by Thomas J. O'Kane with the goal of producing high-performance penetrants. Over the years, the brand expanded beyond penetrating oils to offer products for cleaning, lubrication, rust removal and corrosion protection.
Today, Kroil products are used across a wide range of maintenance applications, including automotive, manufacturing, agriculture, aviation, HVAC, marine, mechanical and industrial environments.
The brand's focus remains closely connected to practical maintenance problems: helping free stuck parts, remove difficult deposits, lubricate mechanisms and deal with rust and corrosion.
What Products Does Kroil Offer?
Penetrants
Penetrants are at the heart of the Kroil product line. These products are designed to work into tight spaces, threads and openings to help loosen rusted or frozen metal components.
The category includes Kroil Original Penetrant, Kroil Clear, Silikroil and Penephite. Different formulations provide different characteristics, such as food-grade requirements, silicone lubrication or graphite-based performance.
Fuel Treatments & Degreasers
Kroil also offers products designed to dissolve and remove difficult substances from engines, mechanisms and surfaces.
Kreen is an all-in-one gas and oil treatment, while Floway is a grease-cutting solvent designed to penetrate, dissolve and remove tough buildup.
Industrial Lubricants
For applications that require dedicated lubrication rather than a penetrating oil, Kroil offers Microil and Pyrolube.
Microil is designed as a precision lubricant for mechanisms and instruments, while Pyrolube is formulated for high-temperature lubrication, with the manufacturer specifying use at temperatures up to 1359°F (700°C).
Rust Solutions
Rust removal and corrosion protection are another important part of the Kroil product range.
Exrust is designed to remove rust, while Kroil Shield provides professional-grade corrosion and rust protection with moisture displacement and a lasting protective barrier.
What Makes Kroil Different?
One of the defining characteristics of Kroil is its long-standing focus on difficult maintenance and repair problems.
Instead of offering only a general-purpose lubricant, the brand has developed products around specific needs such as penetrating seized components, cleaning heavy deposits, precision lubrication, high-temperature lubrication, rust removal and corrosion protection.
Kroil also maintains a broad range of technical and application information for its products, helping users select a formulation based on the type of maintenance task and operating conditions.
The brand's history is another important part of its identity. With roots going back to 1939, Kroil has spent decades developing products around the practical challenges faced by mechanics, maintenance professionals and industrial users.
Why Choose Kroil?
Kroil can be a practical choice for customers who need products designed around specific maintenance problems rather than a single product for every situation.
Whether the task involves freeing a corroded fastener, cleaning difficult deposits, lubricating a precision mechanism, working in high temperatures or protecting metal from rust and corrosion, Kroil offers products developed for these different requirements.
The right product will always depend on the component, material, operating environment and specific maintenance task. Understanding that application first makes it easier to select the appropriate Kroil formulation.
