About CV Technik
CV Technik is an engineering company specialized in the development and production of radial shaft seals (rotary shaft seals) and sealing solutions for industrial applications. The portfolio includes standard oil seals, high-pressure lip seals, heavy-duty oil seals, fabric-reinforced oil seals, PTFE lip seals, VR single and double lip seals, hydraulic seals (piston seals, rod seals and wiper seals, guide rings/bands), O-rings and V-rings, as well as large-diameter seals and rubber sheets. In addition, the company offers engineering services: development of high-pressure and large-diameter rotary shaft seals, seal selection according to pressure, temperature, speed and media compatibility, efficiency enhancement, testing and validation, as well as worldwide distribution with warehousing. The seals are manufactured from NBR, FKM (Viton), MVQ (silicone), PTFE, polyurethane and fabric-reinforced elastomers. CV Technik is represented with a sales and service office in Germany (Head Office Europe) as well as R&D and manufacturing in India, and serves customers worldwide in mechanical engineering, hydraulics and rotating machinery.
