OE Quality for the Automotive Aftermarket

NORMA has the right fluid line in original equipment manufacturer quality for every application in its range.

What are fluid lines?

Fluid lines in a motor vehicle are complete systems that are used to transport various types of fluids or even air within the vehicle. These include water/coolant, fuel, oil, brake fluid and other media.

How are fluid lines designed?

As a transport system for liquids or air, fluid lines consist of a plastic pipe or hose and corresponding connectors, also called quick connectors or quick couplers. These are used to connect and fix the fluid line to the corresponding components in the vehicle. Quick connectors are usually plugged onto a spigot and then snap into place. The pipe or hose and the connector are attached to each other by a spigot or a glued or laser welded connection. It is also possible to fasten the two components with a hose clamp.

In addition to these relatively simple fluid line designs, the automotive industry also uses very complex complete systems with numerous features and system integrations such as sensors and brackets.

When do fluid lines need to be replaced?

The exact service life of fluid lines in a vehicle depends on various factors. Of course, the type of line, its area of use and other parameters such as environmental conditions play an important role.

There are some general guidelines and signs that may indicate that fluid lines need to be replaced:


Visible damage

Inspect the lines for cracks, leaks, dents, or other visible damage. If such problems are found, replacement is necessary.

Age and mileage

As the vehicle ages and the mileage increases, fluid lines tend to wear out. Manufacturers may also recommend in their maintenance guidelines that lines be checked or replaced after a certain mileage.

Malfunctions 

If there are signs of malfunctions in the system, such as difficulty braking or leaks, defective fluid lines may be the cause.

Rubber materials

In older vehicles, rubber lines can become brittle over time. If the lines become brittle or show signs of cracking, they should be replaced.

Fluid loss

An obvious loss of fluid in one of the systems (brakes, cooling system, power steering, etc.) is a clear sign that a line may be leaking.

Marten bite 

If a marten is causing trouble in the vehicle, fluid lines are often damaged and leaks or malfunctions occur.

Accident damage 

It is not uncommon for individual fluid lines, for example in the area of the radiator, to be damaged in an accident. In this case, the repair shop will replace the line.


In many cases, replacement is the safest and most reliable solution, especially when it comes to safety-relevant components such as brakes. Automotive professionals should make sure to use OE parts and spare parts in OE quality to ensure accuracy of fit, quality and durability.

It is important to note that regular maintenance and inspections can allow for the early replacement of worn or damaged fluid lines before more serious problems occur. The manufacturer's specifications and maintenance schedules should always be observed.

Did you already know?

Fluid lines from NORMA are also playing an increasingly important role in electrified powertrains. For example, in the area of water cooling for electric motors, cooling of the high-voltage battery module or cooling systems for power electronics.
