Ozone: Please Close the Ends of Unused Refuelling Hoses

The tube of refuelling hoses is normally of NBR. This elastomer has a weak resistance against ozone. Without protection, the effect of ozone may cause cracks within the tube.

A good protection can be achieved by mixing antioxidants into the tube material during hose production. However, this is not possible for aircraft refuelling hoses.

Consequently, all Yellow Band refuelling hoses -but especially aircraft refuelling hoses- should only be stored and transported with closed ends.
