About Fulton Bellows

A legacy of innovation, precision, and reliability in metal bellows technology since 1904.

Our History

In 1904, Weston Fulton, a visionary meteorologist from the University of Tennessee, introduced the groundbreaking thermodynamic innovation known as the “sylphon,” drawing inspiration from the Norse goddess of weather. This invention marked a pivotal moment in industrial history, catalyzing sweeping changes across various sectors.

The sylphon played a crucial role in advancements made by the Allied forces during World War I and II. Its impact was so profound that the U.S. Patent Office established a dedicated section for sylphon-related spin-offs.

Over the decades, the company evolved through key milestones: acquisition by Reynolds Metals in 1928, independence in 2000, merger with Cliflex Bellows in 2014, and integration into Smiths’ Flex-Tek group in 2019 — all while maintaining its legacy of excellence.
