CRC Industries

<h3>About CRC Industries</h3><p>Few names carry as much weight in the specialty chemicals world as CRC Industries. <strong>Founded in 1958</strong> out of a Pennsylvania garage, CRC — originally short for Corrosion Reaction Consultants — set out to solve one of the most persistent problems in mechanical maintenance: corrosion. What started with a single corrosion inhibitor formula has since grown into a global powerhouse with a catalog of over 1,300 specialty products and formulations.</p><p>Today, CRC Industries is headquartered in Horsham, Pennsylvania, and operates manufacturing and distribution facilities across the United States, Australia, Europe, and Asia — with products sold in more than 120 countries. The company serves a remarkably broad range of industries, including automotive, marine, heavy truck, electrical, industrial, hardware, and aviation — making it one of the most versatile MRO (Maintenance, Repair, and Operations) chemical suppliers in the world.</p><h3>A Legacy of Innovation</h3><p>CRC has built its reputation on being first to market with solutions that professionals actually need. Perhaps the most famous example is <strong>CRC Brakleen&reg;</strong>, which became the number-one selling brake parts cleaner worldwide and set the standard for fast-acting, residue-free brake system cleaning. That same drive for innovation carries through their entire product lineup — from <a href="/1503-crc-industries-brake-cleaner-16751">brake cleaners</a> that feature PowerJet&reg; spray technology to <a href="/1503-crc-industries-automatic-transmission-fluid-11387">automatic transmission fluids and treatments</a> engineered for high-mileage vehicles, to <a href="/1503-crc-industries-gear-oil-201457">gear oils</a> formulated for the rigorous demands of differentials and manual transmissions.</p><p>CRC&apos;s portfolio of trademarked brands — including CRC&reg;, Sta-Lube&reg;, K&amp;W&reg;, Marykate&reg;, SmartWasher&reg;, and Evapo-Rust&reg; — reflects decades of targeted product development across dozens of specialized applications. Whether it&apos;s a professional technician in a busy shop or a weekend DIYer in the driveway, CRC products are engineered to deliver reliable results.</p><h3>Quality You Can Count On</h3><p>CRC Industries operates as an ISO 9001:2015 certified manufacturer, meaning every formulation goes through rigorous quality controls before it reaches the end user. The company&apos;s commitment to health, safety, and environmental compliance is woven into its product development process — an especially important consideration in the highly regulated world of specialty chemicals. CRC also actively invests in the future of the skilled trades through sponsorships and scholarship programs that support the next generation of automotive and industrial technicians.</p><p>With nearly seven decades of chemistry expertise behind every can and bottle, CRC Industries continues to be the brand that mechanics, technicians, and enthusiasts trust when the job has to be done right.</p>

Ordered a Thule hitch and was a little skeptical because I hadn't heard of this company. I was pleasantly surprised by the quickness of response when I ordered, I received an email immediately, and the order arrived just 2 days after it was ordered. This company goes to the top of my list.
