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.

1.Wide range of cords for various applications

2.Availability of unlimited and fully customizable internal diameters

3.High mechanical performance

4.ISO 3601-1 and ISO 3601-3 tolerances

5.Extensive selection of certified materials

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.

We produce O-Rings in all these materials, with certifications for food use (FDA, 3A Sanitary Standards, USP) available and for AED use (Norsok M710). Take note: for VMQ and CR materials the minimum producible cross section is 5,00 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.
