Techné is the parent company. It has been created by Georges Fontaines in the 80s.  
Techné’s primary activity was trading but then Techné chose to diversify its activity. Therefore, at the end of the 80’s, Techné started to produce machined and tailor-made parts.
Techné benefits from a wide stock of standard seals (O-rings, oil seals, bushes…). The company has also the possibility to produce specific machined parts (rod and piston seals, wipers, rubber and plastic seals…).
Techné started to establish subsidiaries mainly in Europe and then in Asia. Techné invests a lot in its subsidiaries so as to increase and upgrade its skills but also in order to best meet the expectations and needs of the customers.
