A flexible lined hose assembly comprises a smooth bore fluorocarbon liner (10) reinforced by a wire (21) which is wound in a single helix with an open pitch at least 1.25 times the wire diameter. Optionally further reinforcement is provided by a wire braid (20) applied either directly to the liner (10) or on to the outside of the helical wire (21), the whole construction then optionally being enclosed within a rubber cover (22) which is not bonded to the liner.
