What Hydrotex does

Hydrotex, founded in 1936 and headquartered in Dallas, Texas, is a specialty lubricant manufacturer that operates as a brand under Whitmore Manufacturing LLC, part of CSW Industrials (NYSE: CSW) following its acquisition on November 5, 2025. The company manufactures and distributes more than 300 proprietary products spanning gear oils, hydraulic fluids, greases, compressor oils, food-grade lubricants, and fuel improvers, serving customers in six primary vertical markets: manufacturing, food processing, agriculture, pupil transportation, sustainable utilities, and fleet operations. The company has 251–500 employees and is privately held as a subsidiary of CSW Industrials.

The company's core technology platform is Hydrosynthetic® base fluids, which combine more than 60 synthetic base stocks with proprietary additive packages to engineer application-specific formulations. Technical assets include NSF H1 and ISO 21469 certification across the Ultra-Kleen™ food-grade line, API and OEM certifications for the HyFilm® LEO engine oils, and registered trademarks covering Hydrosynthetic®, Essentialube® (the 1946 flagship product), Ultra-Kleen™, SYN-Nth™, and the Lubricants for a Healthier Planet™ sustainability line. Lab Services provide fuel and oil analysis using ASTM methods for predictive maintenance and fuel-quality monitoring.

Hydrotex operates a sales-led go-to-market model through a network of independent local representatives across North America, supplemented by Single Source Supply Agreements—1–3 year contracts with monthly payment plans that deliver recurring revenue and budget predictability for customers. Complementary service revenue comes from Lubrication Management consulting, Lubrication University training (including STLE and ICML certification prep), and Clean Diesel Fuel Management—a data-driven fuel-quality program built on a 2015 strategic partnership with Donaldson Company that combines filtration technology, fuel chemistry, and a nationwide fuel-distributor network.
