Our History

Founded in 1930 as L-K Pump Valve Company, L-K Industries has evolved to become one of the most well known names in oil testing.
Our Founder, Louis Hill Kennon, believed that quality products and service were the pillars to building a long-term company, and he was right. Eighty five years later, L-K Industries continues operating with the same guiding principles. In 2015, the company started a new chapter and was acquired by Eric R. Calderon. Upon closing Eric remarked, “It’s a privilege to carry on such a well respected name in the industry. With such a strong operating history, L-K stands well positioned to continue serving customers and making quality products for the next 85 years and beyond”.
