SEAL-TITE CELEBRATES 125 TH ANNIVERSARY WITH RIBBON CUTTING MAY 23,
2025

HILLSBORO, OH. In the spring of 1900, the Peck-Williamson Heating Co. commissioned its
sheet metal shop in downtown Cincinnati and the Seal-Tite brand of galvanized ductwork was
born. Galvanized sheet metal duct, pipe & fittings were needed to distribute air from central
furnace systems to every room in the house. Peck – Williamson (later known as The
Williamson Furnace Co.) was one of the first manufacturers of central furnace systems and
decided to manufacture its own brand of galvanized ductwork.

In 1982 Seal-Tite’s manufacturing plant was moved from Cincinnati to Hillsboro in Highland
County, Ohio. For the past 125 years the finest HVAC technicians and craftsmen have insisted
on installing Seal-Tite, galvanized duct, pipe and fittings. These contractors, their wholesalers
and our customer service, shipping and manufacturing teams have contributed greatly to the
growth and success of Seal-Tite.

As we enter our 125 th year in business we want to thank the HVAC industry, all our customers
and employees and invite each of you to continue to share in our partnership and success in
our future. We will continue to lead the industry with best-in-class quality, on-time delivery and
exceptional customer satisfaction that has been our hallmark for 125 years.

As well Seal-Tite has become a pillar of the Highland County and surrounding communities
and is deeply committed to being an active and responsible employer for both the local
neighborhood and beyond. A strong, thriving community is built upon the contributions of local
businesses, and as such, we strive to not only provide quality products and services but also to
support the growth and development of the next generation of workers. As a company, we take
pride in offering meaningful career opportunities and contributions to the local economy. Our
team is made up of individuals who are passionate about their work, and we are always
looking for ways to engage with the community in a positive and impactful way.
