Rubber hoses play various critical roles in automotive systems. And several types are commonly used in cars. Here are some of the main types of rubber hoses found in vehicles and their functions
Coolant Hose
This radiator hose circulates coolant between the engine, radiator, heater core of the cooling system. It is made of durable rubber to withstand high temp and pressure.
Fuel Hose
Fuel hose carries gasoline or diesel fuel from the fuel tank to the engine. It need to be resistant to the corrosive effects of fuel. Besides, it should be able to withstand the pressure generated by the fuel pump.
Vacuum Hose
Vacuum hose routes vacuum signals from the engine to various components. Such as the brake booster, emission control devices, and HVAC system. These hoses are often smaller in diameter and designed to maintain a tight seal to prevent leaks.
PCV Hoses
PCV hose connects the PCV valve to the intake manifold. Then the engine can vent harmful gases from the crankcase back into the intake for combustion. This hose needs to withstand oil vapors and high temp.
Brake Booster Hose
This hoses connects the intake manifold or vacuum pump to the brake booster. And it provides power assist for braking. It needs to be robust and airtight to ensure reliable brake operation.
Power Steering Hose
It carries fluid between the power steering pump, rack or gearbox and reservoir. It needs to handle high pressure hydraulic fluid without leaking.
Air Intake Hose
Air intake hose delivers filtered air from the air filter housing to the engine’s intake manifold. It is flexible and resistant to heat and vibration.
Heater Hose
Heater hose carries hot coolant from the engine to the heater core inside the vehicle’s cabin. It plays a crucial role in providing heat to the interior during cold weather.
