For 68 years Penray has been a leading aftermarket chemical solutions provider helping customers solve complex problems with innovative chemistry focused on automotive, heavy duty, marine and industrial applications. In 2017, Penray was acquired by PLZ Aeroscience Corporation. The PLZ family of companies formulate, blend, fill and package more than 2,500 brand and private label products. PLZ specializes in the development, manufacturing, packaging and distribution of a comprehensive line of products since 1947.


These products are Penray's premier quality offerings. Formulated for the service professional, they minimize the time it takes to complete repair projects. Uncompromised quality insures customer satisfaction, and absolute top-quality results. Developed for major engine manufacturers, Pencool additives have become the standard of excellence in cooling system technology. The flagship of the Pencool line, the Need-Release filter, is the basis of Penray's Fill-For-Life extended coolant interval maintenance program.
