<p>An elongated multi-layer tubing (10) for connection to a motor vehicle system to handle fluids containing hydrocarbons comprises a substantially smooth, non-convoluted inner layer (14, 14') disposed radially innermost and having an inner surface capable of prolonged exposure to a fluid containing hydrocarbons; and an outer layer (12, 12'), sufficiently convoluted to provide a desired degree of flexibility, the outer layer being substantially non-reactive with an external environment to which it is exposed, and able to substantially withstand shocks, vibrational fatigue, changes in temperature, and exposure to corrosive or degradative compounds. The tubing may also comprise an intermediate bonding and/or barrier layer (16, 16') disposed between the inner layer and the outer layer.</p> |
