Sealing profiles tailored to your needs



Design services

We are continuously developing our services and production lines to serve our customer well and efficiently. We guarantee our customers the highest quality products quickly. Our production includes over 6,000 different types of profiles.

If the standard models are not suited for your needs, we will manufacture tailor-made nozzles according to your sealing requirements. This allows us to provide customized service to all our customers. The nozzles are manufactured with computer-guided machinery according to the drawings provided by our customers themselves or specifications made by our designers.  Using computer-aided machinery, results in excellent precision in the finished product.



OT-Kumi Oy is an experienced and respected manufacturer of sealing products. We are committed to developing our operations and following user experiences received of different sealing materials and profiles. This is the basis of our product development: we invest in it every day. In order to ensure precision and reliable deliveries, we manufacture the nozzles for the sealing profiles ourselves.

Today, the choice of raw material is increasingly more influenced by environmental issues. In recent years, the proportion of the environmental friendly TPE has grown rapidly. This is why we have also systematically invested in the development of these profiles.


Production of upgraded products

In upgrading, the sealing profile designed and manufactured according to the needs of our customers will be finalized into the desired shape, for example, as a hoop, a circle or an angle. For upgrading purposes we manufacture our own coupling moulds in order to produce the desired shape.
