SumiRiko Ohio, Inc, SumiRiko Tennessee, Inc., and S-Riko Automotive Hose de Chihuahua, S.A.P.I. de C.V. supply the automotive industry with top of the line products. Our anti-vibration products enhance comfort, soundscape, and road handling. Our hose products carry fluids while resisting heat and absorbing vibration. Our soundproof/interior products reduce vehicle noise enhancing the driver experience. We are a division of Sumitomo Riko Company Limited that has a wide-reaching footprint in the “Automotive (Mobility)”, “Infrastructure and Housing Environment”, “Electronics”, and “Healthcare”.

SumiRiko Ohio and SumiRiko Tennessee manufactures and sells a wide variety of anti-vibration rubber products such as hydraulic and conventional engine mounts, body mounts, engine drivelines, exhaust isolation mountings, and body isolation products. SumiRiko Tennessee and S-Riko Automotive Hose de Chihuahua also specialize in a complete line of automotive hose products, including rubber and plastic high pressure fuel hoses along with vapor hoses. They also manufacture urethane sound reduction products. Since 1988, we have followed the motto that “Our Associates are our Most Valuable Resource”. We take great pride in satisfying our customer’s needs and provides the highest quality products, competitive prices, and exceptional service.


Our automotive products provide further comfort as well as safety and security to drivers and passengers. Our anti-vibration products enhance comfort, soundscape, and road handling by reducing vibration and noise caused by the engine and road surface.

Anti-vibration Rubber Parts

Our anti-vibration rubber products, manufactured at SumiRiko Ohio and SumiRiko Tennessee use rubber developed using our polymer materials technology, boasting flexibility, damping, and reliability, efficiently absorbing the vibrations from the engine and road surface to help contribute to a comfortable vehicle space.


Our automotive hoses, manufactured at SumiRiko Tennessee run the length and breadth of the inside of vehicle chassis and are prized for their technology which combines rubber and resin. They are used in many parts of the vehicle from around the engine to around the fuel tank due to their superior heat resistance, impact, vibration absorption, and lightweight properties.

Interior Equipment & Sound Controlling

Manufactured at SumiRiko Tennessee and S-Riko Automotive Hose de Chihuahua, the inside equipment in automobiles directly contacts the body of the user, so apart from the obvious requirements for safety, it is also important that the equipment satisfies the five senses. We manufacture interior parts such as headrests and armrests that have a pleasant texture but also have excellent shock resistance.

Research and Development

The properties and characteristics required of products are becoming more sophisticated, with more demands for safety, comfort, and environmental compliance. One of our core competencies is “polymer materials technology”, which is based on the technologies of compounding, synthesizing, and modifying, and we will use this to provide solutions to the demands of society through research and development to create new functional materials and parts.

Design and Analysis

Product design technology that ensures the final product, not just the individual parts, meet the required performance and reliability benchmarks. Along with this is our CAE analysis technology that enables precise performance predictions and optimized design for our rubber and resin products. By making the most of such technology at the design stage, we can foresee the needs of our customers so that we are able to develop and provide even more reliable, even higher quality products.

Prototypes and Evaluation

As a system supplier, our core competency, “Comprehensive Evaluation Technology”, is the process of analyzing and verifying materials, meticulously and from a variety of perspectives. For example, we have established evaluation technology for evaluating a completed vehicle with all the parts fitted which gives us an insight into the necessity of the part that we cannot see by just examining the part by itself, and this enables us to accurately perceive the sophisticated needs of the end user, our customers, and provide solutions while providing products with a high degree of reliability.
