Specifications and models of rubber hoses used in automobiles

The rubber hose used in automobiles is an important transmission device and is widely used in automobile engines, air conditioning systems, braking systems, hydraulic systems and other fields. The specifications and models of rubber hoses are crucial to the normal operation of the car. This article will introduce in detail the classification, specifications, materials, uses, etc. of rubber hoses. 1. Classification of rubber hoses According to different usage environments and functions, rubber hoses can be divided into the following types: Oil pipes: hoses used to connect the engine and the fuel tank, oil pump, and oil filter. Hydraulic pipes: Hydraulic oil pipes, brake fluid pipes, etc. used in automobile hydraulic systems. Air conditioning pipe: A hose used to connect the refrigerant medium, condenser, evaporator, compressor and other parts of the automobile air conditioning system. Water pipe: A hose used to connect the water tank, water pump, radiator, air intake and other parts of the car cooling system. Air pipe: A hose used to connect the intake pipe, air filter, throttle and other parts of the car’s air intake system. 2. Specifications and models of rubber hoses The specifications and models of rubber hoses are important parameters in automobile maintenance. Different specifications and models play a very important role in the normal operation of the car.

The specifications and models of rubber hoses usually consist of inner diameter, wall thickness, length and other parameters. Common specifications and models are: Inner diameter: The inner diameter of a rubber hose refers to the diameter of the internal space of the hose, and the general unit is millimeters (mm). Common inner diameters are: 6mm, 8mm, 10mm, 12mm, 16mm, etc. Wall thickness: The wall thickness of a rubber hose refers to the thickness of the hose wall, generally in millimeters (mm). Common wall thicknesses are: 1.5mm, 2mm, 2.5mm, 3mm, etc. Length: The length of rubber hose is generally measured in meters (m). Common lengths are: 0.5m, 1m, 1.5m, 2m, etc. Bending radius: The bending radius of a rubber hose refers to the minimum radius required when the hose is bent. Common bending radii are: 30mm, 50mm, 100mm, 150mm, etc. Pressure-bearing capacity: The pressure-bearing capacity of a rubber hose refers to the maximum pressure that the hose can withstand. Common pressure-bearing capacities are: 1.0MPa, 1.5MPa, 2.0MPa, 3.0MPa, etc. 3. Material of rubber hose The material of rubber hose has an important influence on its service life and performance. Common rubber materials are: Butyl rubber: has excellent oil resistance, wear resistance and cold resistance. Neoprene: has excellent oil resistance, corrosion resistance and heat resistance. Ethylene-propylene rubber: has excellent heat resistance, cold resistance, and wear resistance. Polyurethane: has excellent wear resistance, oil resistance and high temperature resistance. Fluorine rubber: has excellent chemical corrosion resistance, high temperature resistance and oil resistance. Different rubber materials have different characteristics and application ranges. The material of rubber hose needs to be selected according to the specific use environment and needs. 4. Use of rubber hoses Engine oil pipes: Rubber hoses are widely used in the lubrication system of automobile engines and are used to connect the hoses between the engine and the fuel tank, oil pump, and oil filter. Hydraulic oil pipe: Rubber hose is also widely used in automotive hydraulic systems, such as brake fluid pipes, high-pressure hydraulic pipes, etc. Air conditioning system: Rubber hoses are also widely used in automobile air conditioning systems, such as refrigerant pipes, condenser pipes, evaporator pipes, etc. Cooling system: Rubber hoses are also widely used in automobile cooling systems, such as water pipes connecting water tanks, water pumps, radiators, air intakes, etc. Air intake system: Rubber hoses are also widely used in automobile air intake systems, such as air pipes connecting air intake pipes, air filters, throttles, etc. In short, rubber hoses play a very important role in automobile manufacturing and maintenance. The selection of specifications, materials, uses, etc. will have an impact on the performance and safety of the automobile. Therefore, when selecting rubber hoses, you need to choose according to specific needs and environments to ensure that the quality and performance of the hoses meet the requirements of the car.
