Purpose and function in the air conditioning system

The presented pipe belongs to the Air conditioning pipes, hoses, and connectors group and is responsible for transporting refrigerant in the high-pressure section of the A/C system. In the BMW i3 I01 Rex Hybrid, a correctly selected pressure line is crucial for maintaining the proper operating pressure, correct compressor operation, and efficient cabin cooling.

The original design of the pipe minimizes the risk of leaks, improper routing in the engine bay, and unwanted stress, which is particularly important in a vehicle with an electric drivetrain and an additional Rex generator.

Construction and advantages of the original BMW pipe

The high-pressure pipe was designed by the vehicle manufacturer, taking into account the specific routing of the installation in the i3 I01 Rex Hybrid model. It includes both rigid and flexible sections, as well as factory connectors matched to the A/C system ports, allowing for installation without any modifications.

• Factory ends and connectors matched to the BMW i3 I01 Rex Hybrid A/C system.
• Pipe geometry consistent with the original installation routing in the body.
• Solution designed for the pressure requirements of the air conditioning system.

As a result, the pipe maintains proper tightness and stability, and installation is predictable and repeatable for the service technician.

Condition, installation, and service application

The item is offered as a used OEM component, which allows for cost-effective air conditioning system repair while maintaining the manufacturer's original specifications. This is a practical solution in the event of mechanical pipe damage, connector corrosion, or leaks detected during a pressure test.

The pipe is intended for direct replacement of the factory element in the BMW i3 I01 Rex Hybrid. In service practice, it will prove useful both for standard repairs following a refrigerant leak and for larger tasks, such as replacing the compressor or condenser, where the system must be opened.

Benefits of using an original A/C line

Using an original high-pressure pipe in the BMW i3 I01 Rex Hybrid allows for maintaining system operating parameters in accordance with the manufacturer's design. This is particularly important in electric vehicles, where the air conditioning system works in conjunction with interior and component temperature management systems.

• Reduced risk of leaks compared to non-original replacements.
• No need to adjust the length or shape of the pipe.
• Consistency with factory BMW service documentation.

For workshops specializing in the BMW brand and users who care about compliance with factory specifications, this is a technically safe and operationally predictable solution.
