O-Rings

O-Rings are used in a wide variety of applications and are one of the core products of today`s sealing technology. The choice of the right material and size can make the difference whether a system is running smoothly for a prolonged duration or forced to stop for maintenance.

O-rings are used in many different industries, and can measure from small standard dimensions of a few millimetres or inches up to ring diameters of over 20 meters. We stock thousands of different sizes and a wide variety of plastic and sealing materials.

We additionally also have the possibility of producing o-rings directly in our workshop.
