History

Whitmore Manufacturing was established by Samuel Whitmore in Cleveland, Ohio, in 1893. The company began as a provider of lubrication products for industrial applications and quickly gained recognition for its ability to solve difficult lubrication problems. In 1904, Whitmore was awarded the contract to support mining lubrication for the digging of the Panama Canal, and its products lubricated 48 miles of lock gates. This early project helped establish Whitmore as a trusted supplier for large-scale infrastructure. Throughout the 20th century, Whitmore expanded its product line and geographic reach. Its lubricants were used in iconic projects such as the Golden Gate Bridge, the London Underground, and NASA's Apollo rockets and space shuttles. The company also became a major supplier to the rail industry, with its products applied on over 60,000 miles of rail line. In 1949, Jet-Lube began operations, eventually becoming a key brand within the Whitmore family, focusing on performance lubricants, anti-seizes, thread compounds, and sealants for oil and gas, construction, water-well, and mining industries. In 1979, Whitmore Manufacturing was acquired by Capital Southwest Corporation. This ownership provided a foundation for further growth and investment. In 2015, Whitmore became part of CSW Industrials, Inc. (NYSE: CSW), a diversified industrial growth company. Under CSW, Whitmore plays a leading role in the Specialized Reliability Solutions segment. The Whitmore Manufacturing, LLC portfolio now includes trusted brands such as Whitmore, Jet-Lube, Deacon, Air Sentry, and OilSafe. Since the late 1980s, Whitmore has been regarded as an industry leader in the development of eco-friendly high-performance products. The company is fully compliant with and monitored by the Texas Commission on Environmental Quality, the Texas Department of State Health Services, and the Environmental Protection Agency. It operates as an ISO 9001:2015 and ISO 14001:2015 facility. Today, Whitmore serves customers in 120 countries through a worldwide network of distributors, with offices in the United States, United Kingdom, and Canada. Its products continue to be used in the most adverse conditions and demanding environments, maintaining the company's reputation for quality, dependable service, and customer satisfaction.
