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 Fits Right! Our unique fabrication process is based on 25 years of testing and development, resulting in the best designed insulation covers utilizing the best materials. Our removable and reusable insulation covers are manufactured in Evansville, Indiana, a city in the heart of the Midwest. Fit Tight Covers is proud to be owned, managed, and staffed locally. Unlike most removable insulation, 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.
