Nupak Oakum Products for Plumbing, Marine & Construction Industries
Nupak Oakum has been a trusted manufacturer of high-quality oakum products since 1953, serving diverse industries across the United States. Founded in Kenner, Louisiana, our company revolutionized traditional oakum by incorporating Bentonite, a natural clay that expands upon contact with water to create superior leak resistance. This innovation, developed by Duane H. Tollstrup, remains central to our product line, which meets federal specifications for performance and reliability. Our brown oakum, formulated with burlap, oil, and Bentonite, prevents 'spitting' during hot lead applications, while our white oakum combines jute roving, Bentonite, and trace water specifically for plumbing applications.We serve plumbing, marine, construction, equine, and log home industries with pre-cut, ready-to-use oakum that simplifies sealing and caulking processes. Our commitment to quality is demonstrated through rigorous compliance with federal standards and decades of customer satisfaction. As the original creators of pre-cut oakum, we continue to lead the market with products designed for efficiency and durability. Our facility in Kenner, Louisiana, remains the heart of our operations, ensuring American-made quality in every batch produced. We provide technical documentation, including MSDS sheets, to support safe and effective product use across multiple sectors.
