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.
1950s — A Global Standard Emerges
In the 1950s, the AS568 standard created a universal system for O-ring dimensions, ensuring parts fit and function seamlessly across manufacturers.
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.
