O rings are elastomer rings with a circular cross-section. They withstand various types of stress, and are resistant to changes in both the O-ring section and its diameters. These characteristics make them amongst the finest seals of all in terms of flexibility. For this reason, they are extensively used in industry, for static, dynamic, axial and radial applications.

O-ring. Over a century’s history in Europe and the USA

The technological innovation that hallmarks O-rings is the result of a history lasting for over a century. In fact, the first patent filed for an o ring by Swedish inventor J.O. Lundberg dates back to 1896.

Almost fifty years later, O-rings crossed the ocean: it was Danish machinist and inventor Niels Christensen who filed a patent for O-rings in the USA, in addition to having patented an air brake used on trams. Though he conducted a long legal battle to retain the patent rights for O-rings, the intellectual ownership of this technology was assigned to a number of organisations, comprising even the Westinghouse company.

When the Second World War broke out, the United States government included O-rings amongst the products considered essential for the war effort, giving many manufacturers the possibility of making them. By way of compensation for his intellectual property, Christensen was paid $75,000, followed by an additional payment to his heirs, but only after many law suits.

O-rings today. ORINGONE and its technological innovation

From Lundberg’s and Christensen’s patents right through to today, O-rings have developed considerably, reaching high standards of technological innovation.
