AC hoses and connectors – reliable parts for car cooling systems

AC hoses and connectors – reliable parts for car cooling systems

High-quality air conditioning components – durability and compatibility with various models

Air conditioning hoses, lines, and connectors play a crucial role in the proper functioning of the air conditioning system. They ensure the tight and efficient transfer of refrigerant between the compressor, condenser, evaporator, and other system components. Their high quality and technical condition are essential for reliable air conditioning operation. At Global Parts, we offer a wide selection of used car parts. , including air conditioning pipes, hoses and connectors, perfectly matched to the brands BMW , Audi , Mercedes, Volkswagen , Mini and many others .

How do the pipes, hoses and connectors in an air conditioning system work?

Air conditioning lines, hoses, and connectors are responsible for the leak-free transfer of refrigerant and lubricating oil between individual system components. Each of these components has a unique role:

  • High Pressure Hoses – Transports refrigerant at high pressure from the compressor to the condenser.
  • Low Pressure Hoses – Carry the refrigerant from the evaporator to the compressor after cooling.
  • Connectors – Provide tight and stable connections between wires and other system components.
  • Seals and O-rings – Protect against refrigerant leaks, ensuring the tightness of the entire system. Each of these components must be made of materials resistant to high pressure, temperature and the chemical properties of the refrigerant.

Definitions and parameters

Air conditioning hoses vary in diameter (usually from 8 mm to 16 mm internal diameter), pressure resistance (up to 35 bar for high-pressure hoses), and termination type . Connectors most often use SAE standards or brand-specific quick connectors, which impacts compressor and condenser compatibility. In practice, this means that a hose for a BMW 5 Series (E60) will not fit an Audi A6 C6, even though both vehicles have similar engine displacement and air conditioning performance.

Why is it worth taking care of air conditioning pipes, hoses and connectors?

The tightness and functionality of air conditioning lines, hoses, and connectors are essential for the reliable operation of the entire system. Their damage or wear can lead to:

  • Loss of refrigerant, which reduces cooling efficiency.
  • Pressure drop in the system, which may damage the compressor.
  • Corrosion due to refrigerant leaks and moisture. At Global Parts we offer genuine used car parts , which have undergone detailed quality tests, ensuring their full functionality and durability.

Comparison of different cables

It's important to distinguish air conditioning hoses from other components of a vehicle's cooling system. Coolant hoses, or cooling system hoses, transport coolant, while oil cooler hoses are responsible for maintaining the correct engine and transmission temperature . For air conditioning hoses, resistance to chemical agents (e.g., R134a, R1234yf) and leak-tightness are key, while for coolant hoses, temperature resistance up to 120–130°C is paramount.

How to choose the right air conditioning hoses, pipes and connectors?

When selecting air conditioning hoses, pipes and connectors, there are several key aspects to consider:

  • Vehicle-specific fit – Every car make and model has specific air conditioning system requirements. At Global Parts, you'll find air conditioning hoses, lines, and connectors perfectly suited to BMW , Audi , Mercedes, Volkswagen , Mini, and many others .
  • Technical condition – Make sure lines and hoses are free from cracks, corrosion and leaks.
  • Connector Type – Choose connectors compatible with your vehicle’s air conditioning system to ensure tight and stable connections.

Why choose used air conditioning hoses, pipes and connectors?

Purchase of used car parts is the perfect solution that combines high quality with cost-effectiveness. When choosing used cables, hoses, and connectors, , you gain:

  • Lower costs – Used parts are cheaper than new ones, but offer the same high quality.
  • Ecology – You support recycling and reduce the amount of automotive waste.
  • A wide range of products – In our store you will find parts for the most popular car brands, making it easy to match them to your vehicle.

How to take care of air conditioning pipes, hoses and connectors?

To ensure that cables, hoses and connectors function properly for a long time, it is worth following a few rules:

  • Regularly check the visual condition of lines and hoses for signs of wear such as cracks or leaks.
  • Replace seals and O-rings whenever the air conditioning system is repaired or serviced.
  • Keep the system clean to avoid contamination that can lead to damage or leaks. In case of breakdown or replacement, you will find the right used car parts at Global Parts that will help restore the full functionality of your air conditioning system.

FAQ - Frequently asked questions about air conditioning hoses, pipes and connectors

QuestionAnswer
What is the air conditioning hose for?It is a flexible or rigid element of the system that is responsible for the transport of refrigerant and lubricating oil between the compressor, condenser and evaporator.
What is the difference between a high-pressure and a low-pressure hose?The high-pressure line carries the refrigerant at pressures of up to 35 bar, while the low-pressure line operates at a value of approximately 5–10 bar and is responsible for returning the cooled refrigerant to the compressor.
What are air conditioning connectors for?Connectors ensure tight connections between pipes and individual system components, e.g. compressor or condenser.
How do I check the compatibility of the cable with my car?It's best to match the part by its OEM number or using the manufacturer's catalog. At Global Parts, you can also do this by entering the vehicle's VIN.
Do air conditioning hoses differ depending on the car brand?Yes, the cable design and connector type vary by manufacturer. For example, Mercedes often uses different terminations than Volkswagens.
What are the symptoms of a damaged air conditioning hose?Decreased cooling efficiency, noisier compressor operation or visible traces of oil and refrigerant in the engine compartment.
Can air conditioning hoses be used interchangeably with refrigeration or oil hoses?No – each type of hose is designed for a different medium (refrigerant, coolant fluid, oil). Using them interchangeably could lead to failure.
