OringOne is the benchmark in the large O-ring market. Thanks to our production system, CO.SM.O, the result of years of research and continuous updates, we can produce O-rings of infinite sizes, with significant cost reductions and maximum flexibility.
CO.SM.O is our trademark, demonstrating our ongoing commitment to research and the development of a unique molding system on the market, capable of meeting the most demanding performance requirements. CO.SM.O eliminates limitations related to size, mold costs, and does not require minimum purchase quantities or amounts.
The CO.SM.O system can only be used with O-ring cross sections of 2.62 mm and a minimum internal diameter of 200.00 mm.
OringOne participated in the development of the world's first optical measuring machines for large O-Rings. This allowed us to be among the first to provide customers with the ability to check the surface defects, internal diameter and cord of our O-Rings with extreme precision. The checks performed using optical machines are conducted upon request.
Cross sections available (in mm)
Our Large O-rings comply with ISO 3601-1 class B and ISO 3601-3 grade N. More restrictive dimensional and defect tolerances according to ISO 3601-1 class A and ISO 3601-3 grade S are confirmed on request.
