<h3>About CRC Industries</h3><p>Few names in the chemical maintenance world carry as much weight as <strong>CRC Industries</strong>. Founded in 1958 as Corrosion Reaction Consultants, the company began with a single product — a corrosion inhibitor that would go on to become an industry icon — and has since grown into a global powerhouse with a catalog of over 1,300 specialty chemical formulations. Headquartered in Horsham, Pennsylvania, CRC serves professionals and do-it-yourselfers across automotive, marine, heavy truck, electrical, industrial, hardware, and aviation markets.</p><p>What sets CRC apart is a relentless commitment to formulation quality and application-specific engineering. Rather than offering generic solutions, CRC develops products tailored to precise service needs — from drivetrain fluids to corrosion protection coatings. The company operates under several trusted trademarked sub-brands, including Sta-Lube&reg;, K&amp;W&reg;, SmartWasher&reg;, MaryKate&reg;, Evapo-Rust&reg;, and Brakleen&reg;, each targeting a distinct segment of the maintenance and repair market.</p><h3>CRC Automotive Chemical Coverage</h3><p>In the automotive aftermarket, CRC&apos;s product line spans virtually every major service category. Technicians and home mechanics alike rely on CRC for brake system care, fuel system maintenance, electrical diagnostics, cooling system service, and complete <a href="/1503-crc-industries-automatic-transmission-fluid-11387">automatic transmission fluid</a> solutions. The brand&apos;s drivetrain coverage extends to <a href="/1503-crc-industries-gear-oil-11394">gear oil</a> formulations under the Sta-Lube&reg; banner, which offers API/GL-rated multi-purpose gear oils suitable for differentials, manual transmissions, and transfer cases.</p><p>Protecting your vehicle from the elements is equally central to what CRC does. Their lineup of <a href="/1503-crc-industries-rust-and-corrosion-inhibitor-19514">rust and corrosion inhibitors</a> dates back to the brand&apos;s very founding — it&apos;s in their DNA. These products shield metal surfaces, stored engine components, and exposed hardware from salt spray, humidity, and oxidation. For drivers dealing with more serious mechanical issues, CRC also offers <a href="/17323-head-gasket-and-block-repair-liquid-crc-industries-1503">head gasket and block repair liquids</a> through the K&amp;W&reg; brand, providing a reliable chemical solution for cooling system leaks and minor engine sealing problems.</p><p>CRC&apos;s reach also extends to everyday vehicle upkeep. Their <a href="/10585-washer-fluid-reservoir-crc-industries-1503">washer fluid reservoir</a> products help maintain clear visibility year-round — a simple but critical aspect of vehicle safety. Whether you&apos;re a professional technician stocking a service bay or a weekend mechanic maintaining a daily driver, CRC&apos;s depth of coverage means fewer trips to multiple suppliers and more confidence in every application.</p><h3>A Legacy of Innovation</h3><p>Over six decades of formulation expertise have earned CRC a reputation that resonates across industries and continents. The brand operates manufacturing facilities around the world and continues to introduce new chemistries to keep pace with modern vehicle technology, evolving environmental standards, and the needs of today&apos;s maintenance professionals.
