This specification applies to plastic tubings with locally corrugated areas to increase flexibility, that are suitable for all commercial petrol and diesel fuels. The installation area in the vehicle are the engine comparment and tank area. The tubings include their connections to the tank and vent systems. For tubing structure see paragraph 4.1.

Direct contact between the fuel tubings and materials containing chlorine, as for example adhesive tapes made of PVC is not allowed, because nascent chlorine resulting from high temperature decomposition may cause cracks in the PA12 outer layer.

The operating temperature range of the tubing is (-40...+100) °C with peak temperatures up to +120 °C. In areas at risk of stone impacts the operating temperature range of the tubing is reduced to (-30...+100) °C. The operating pressure is less or equal to 2 bar.
