Since the spring of 1900, the finest HVAC technicians and craftsmen have insisted on installing Seal-Tite®, prefabricated galvanized duct, pipe & fittings. These contractors, their wholesalers, and our employees have contributed greatly to the growth and success of Seal-Tite®. We thank all of those who have made the last 118 years a success and invite you to continue to share in our partnership and success in the future.
