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 combine 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 and vibration absorption and light weight properties.

Rubber Fuel Hoses

These products are mainly used around the engine and fuel tank, so require the use of materials with extremely good fuel resistance and durable structures. They are used in extremely severe environments where flexibility is required.

Resin Fuel Hoses

This product is mainly used around the engine and fuel tank. These resin hoses have low permeability and are made up of multiple layers of polymer materials, complying with the world’s strictest gasoline evaporation regulations.


These are mainly found around the gasoline tank, repeatedly absorbing and releasing gasoline vapor. They comply with the world’s strictest gasoline evaporation regulations.


Air Control Hoses

We have developed the polymer materials technology to make these hoses extremely heat resistant. The product line-up includes heat-resistant turbo air hoses for attachment to ultra-high-temperature turbo chargers.

Water Hoses

These water line hoses include radiator and heater hoses. We use polymer materials technology to make them extremely heat resistant.

Oil Hoses

This product is expected to be highly heat-resistant due to the extreme heat in the environment it is used. It maximizes the performance of automatic transmission systems and contributes to the fuel efficiency of the vehicle. It is used in circuits that maintain transmission fluids at a constant temperature.

Air Conditioning Hoses

These hoses are used in refrigerant circulation systems for automobile air conditioning. Advanced technology is used to attach aluminum fittings to both ends of a flexible hose.

Hydrogen Hoses

Hydrogen hoses are used to transport hard to seal small gaseous matter at high pressure. Installed in fuel cell vehicles (FCEV), these hoses require a high level of reliability and durability to ensure that hydrogen is not leaked outside the vehicle under any circumstances.
