Anti-vibration Rubber

Sumitomo Riko's anti-vibration rubber products use rubber developed using our polymer materials technology, boasting flexibility, damping, and reliability, efficiently abs orbing the vibrations from the engine and road surface to help contribute to a comfortable vehicle space.
We acquired the German automotive anti-vibration rubber maker Anvis in 2013, turning it into a consolidated subsidiary. This has given us further strength to market our products to overseas automobile manufacturers as well as Japanese ones.

Dynamic Dampers

Installed in automotive subassemblies, devices which control vibrational eigenvalues suppress vibration to deliver more comfortable and quieter driving.

Hoses

Pipes running the length and breadth of the inside of vehicle chassis. The hoses for vehicles from Sumitomo Riko are prized for their technology which combines rubber and resins. They have superior heat resistance, impact and vibration absorbing properties, and in their weight. They are used in many parts of the vehicle from around the engine to around the fuel tank. With many manufacturers using common parts and platforms, parts makers are expected to develop and propose systems rather than just individual parts. In order to acquire the technology to design modules as a whole along with peripheral parts, in 2013 we acquired the Italian hose man ufacturer Dytech and turned it into a consolidated subsidiary. By accelerating the fusion with our high-polymer materials technology and taking advantage of each others branch networks and marketing channels, we will create new technologie s and new products.

Rubber Fuel Hoses

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 very extreme environments where flexibility is required.

Resin Fuel Hoses

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, com plying with the world's strictest gasoline evaporation regulations.

Canisters

Canisters

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

Oil hoses

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 turbochargers.

Water Hoses

Water Hoses

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

Oil Hoses

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

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.

Power Steering Hoses

Power Steering Hoses

It is anticipated that these hoses will operate under extremes of temperature and pressure, so these high-oil pressure hoses are made from materials with excellent heat resistance. The pulse reduction construction is a characteristic of this series that is used in the fluid circulation circuits of oil-based power steering systems.

Sound Controlling/Insulation Products

There are many sources of noise in an automobile, including engine. Sumitomo Riko sound controlling and insulation products shut out these noises and keep the inside of the cabin quiet. Urethane is used for the engine cover due to its heat resistant and sound absorption and insulating properties, realizing a high degree of noise reduction even on the engine parts with high temperatures.

Engine Covers

Engine Covers

Installing a cover over the top of the engine reduces engine noise. We use materials with excellent heat-resistant and fire proofing properties to enable applications at extremely high temperatures. Optimized cover design also contributes to an improved engine compartment appearance.

Standing Wave Spacers

Standing Wave Spacers

These products fill airspace to reduce noise generated in gaps between the engine body and its peripheral equipment. Our mold-casting technology enables fitting in to spaces with complex shapes.

Interior Equipment

Inside equipment in automobiles directly contacts the body of t he 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 resi stance.

Headrests

Headrests

Our interior equipment contributes to comfort and safety in the car. Our unique urethane material and comprehensive production capabilities covering the entire manufacturing processes from cutting, sewing to integrated foaming result in products of consistently high quality.

Armrests

Armrests

Situated on the central parts of the doors on both sides, these provide comfort during the ride by proving a place to rest your arm . We adopt integrated molding techniques with outstanding design flexibility to provide products that provide comfort to drivers and passengers.

Seal Products

There are bundles of cables that carry power and signals and wire harnesses threaded throughout vehicles. There are about 500 waterproof seals used in each vehicle for the wire harnesses in and around the car, and we are able to provide a stable supply of these using our precision rubber molding technology and quality assurance system.

Connector Seals

Connector Seals

These waterproof connector seals are fastened to wire harnesses. Precision metal molding and liquid silicone molding technologies eliminate burrs and losses. In-line inspection assures the quality of all seals.

Wire Seals
