Celebrating Movers and Shakers Innovations
This is Harry Railton. I have been involved in the O-Ring and Seal supply chain for more than 6 decades. Over the years I have met or heard of many of the characters in the global growth of the business.
Compiling the O-Ring & Seal Hall of Fame has been quite a challenge but also very enjoyable. Should anyone have suggestions for further additions please send the name along with a brief bio – Harry@finnglobalsupply.com

Historic Milestones
1896 — The First Ring-Shaped Seal Patent
J.O. Lundberg’s early design in Sweden laid the groundwork for the modern O-ring.
1933 — A Brilliant Idea Takes Shape
Niels Christensen starts experimenting with rubber rings for hydraulic systems — sparking the birth of the O-ring.
1939 — A Breakthrough in Sealing Technology
Christensen patented a simple, reliable O-ring geometry that became the foundation of modern sealing technology.
WWII — The O-Ring Takes Flight
WWII — O-Ring Goes to War: The U.S. government acquired Christensen’s patent, making it royalty-free for military use and accelerating its adoption in aircraft and defense.
Post World War II — A Seal Goes Global
After proving itself in military use, the O-ring spread across industries worldwide — saving millions in maintenance and repair.
1950's — A Global Standard Emerges
In the 1950’s, the ARP 568 standard was created. A universal system for O-ring dimensions, ensuring parts fit and function seamlessly across manufacturers. This nomenclature was later changed to AS568.
1986 — O-Rings in Space
O-rings have journeyed far beyond Earth, trusted in critical aerospace missions — from the Space Shuttle to the International Space Station.
Advancing O-ring performance
Engineers continue to advance O-ring technology by developing new materials such as FFKM and encapsulated designs. These innovations allow seals to withstand increasingly harsh chemicals, extreme temperatures, and demanding environments—ensuring reliable performance where it matters most.
