We design and manufacture removable and reusable thermal insulation covers for commercial and industrial mechanical piping and equipment. Our high-quality covers help reduce energy costs and maintain process temperatures while simplifying access to critical components for maintenance and inspection. Fit Tight Covers fit the best because they are sewn in the actual shape of the equipment, whether that is a single valve or an entire piping system. By custom-engineering every cover for each customer, our products will fit your system perfectly. Our unique fabrication process, based on 25 years of testing and development, ensures the best-designed insulation covers using the finest materials. Manufactured in Evansville, Indiana, in the heart of the Midwest, Fit Tight Covers is proud to be locally owned, managed, and staffed.
