About Airtomic ® - Sealing Solutions

The Airtomic Story In 1888 Charles Lee Cook founded The C. Lee Cook Company in Louisville, KY producing the first metallic packing used on piston rods for locomotives and steamships. In time the C. Lee Cook Company designed and manufactured a variety of sealing ring products and went on to become a founding company of a multi-billion dollar manufacturing conglomerate and was then consolidated into Cook Airtomic.

In 2001 Cook Airtomic relocated to Jeffersonville, Indiana producing piston rings, sealing rings, tubes, ducts, and manifolds, for the aerospace and defense, power generation and nuclear energy markets. In 2002 Cook Airtomic joined Sargent Aerospace and Defense and was renamed Airtomic.
