What characteristics are critical when selecting materials for fuel lines?

When selecting materials for fuel lines, chemical resistance and temperature tolerance are critical characteristics. Fuel lines must be able to handle various types of fuel without degrading or reacting negatively with the chemicals present. This resistance ensures that the integrity of the fuel lines is maintained over time, preventing leaks and potential hazards.

Temperature tolerance is equally important as fuel lines may be exposed to a range of temperatures depending on the environment and the operation of the engine or equipment. If a material cannot withstand high temperatures, it may become brittle or deform, leading to failures in the fuel delivery system.

The combination of these two characteristics—chemical resistance and temperature tolerance—ensures that the fuel lines perform reliably and safely under the conditions they will face in service. This focus on the physical and chemical properties of the materials directly impacts the safety and efficiency of fuel systems.
