About BestFitt Products
In 1984, while Steve Jobs was introducing his first MacIntosh computer to the world, the Davis family of BestFitt Gasket opened its doors to the local precast industry. Since then, contractors have installed hundreds of thousands of BestFitt gaskets in concrete manholes and pipe. We welcome you to the new BestFitt as we focus on product expansion, online ordering, and continued customer service and support. As we build our new website, please contact us for any product inquiries or technical questions.
