Plastic Fuel Filler Pipe

Plastic Fuel Filler Pipe

These pipes convey fuel to the fuel tank. They function for the smooth flow of fuel and to prevent backflow.

Capless Fuel Filler

Capless Fuel Filler

A device designed to make refueling more convenient by simply inserting the nozzle without opening or closing the filler cap when refueling.

Fuel Filler Cap

Fuel Filler Cap

These caps are attached to prevent fuel leakage from the intake port when the gas pump nozzle is inserted, by functioning as a seal.

Fuel Hoses and Tubes

Fuel Hoses and Tubes

These rubber and plastic pipes send fuel to the engine and fuel vapor to the atmosphere via the fuel vapor cleaner.

Inlet Check Valves

Inlet Check Valves

Check valves prevent fuel from flowing backwards out of the fill tube opening when the tank becomes full.

Roll Over Valves

Roll Over Valves

Rollover valves have a sealing function that prevents fuel spills from the fuel tank in the event of a vehicle rollover.

Fill Limit Vent Valve

Fill Limit Vent Valve

These valves restrict the amount of fuel when the tank becomes full, functioning to seal and prevent variation in fuel levels.

Fuel Filler Lid

Fuel Filler Lid

In addition to protecting the fuel intake port from dust and water, fuel filler lids improve the aesthetic quality of the body and the ease of use of the fuel intake cover.

Air Cleaner Hoses and Resonators

Air Cleaner Hoses and Resonators

Air cleaner hoses are used in providing the clean air needed for engine revolution. Resonators reduce the noise that is generated when air is taken in.

Noise Absorbing Air Intake Ducts

Noise Absorbing Air Intake Ducts

These ducts take in outside air needed in engine revolution. Intake noise is reduced with the use of air permeable members in part of the duct.

Reservoir Tanks

Reservoir Tanks

Reservoir tanks are injection molded, hot plate welded containers used to hold excess or overflowing engine coolant. They can be used in a pressurized or open system.

Engine Covers

Engine Covers

By covering the top of the engine, these covers make the engine compartment more aesthetically pleasing and reduce noise from the engine itself.

Radiator Hoses

Radiator Hoses

These hoses connect the engine and radiator for the circulation of the coolant that is needed to cool the engine.

Plastic Water Pipes

Plastic Water Pipes

These pipes are placed around the engine. They include several types with different functions. They are used for air conditioning, oil cooling, turbo cooling and other functions.

Turbo Ducts

Turbo Ducts

Turbo ducts direct supercharging air to the engine by turbo to improve engine power. They are pressure and heat resistant.

Brake Hoses

Brake Hoses

These hoses transmit hydraulic pressure in the body-side brake system to the wheel-side brake system. They are flexible and highly durable so that they can follow the movement of the wheels.
