Aircraft — High temperature convoluted hose assemblies in polytetrafluoroethylene (PTFE)

Gives characteristics of these assemblies for use in aircraft fluid systems at temperatures between -55 and +200 °C and at nominal pressures, depending on bore size, up to 6,8 MPa. Special approval from the proper national authority may be required it these hoses are to be part of a pressurized gas storage system. Two types of hose assembly are covered: Typ 1 – non-conductive inner tube and type 2 – conductive inner tube.
