Airtomic has extensive experience in material selection and ring design that offers superior ring life and leakage control.

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.Airtomic - Sealing Solutions

Airtomic designs and manufactures piston rings installed on landing gear hydraulic snubber actuators. These rings can see extremely high pressure in operation. Snubber rings can be found on landing gear used on: Aircraft Rotorcraft Snubber rings are typically made from bronze alloys for wear compatibility with actuator shafts and cylinders.
