Abstract: A fluid conduit including an inner layer is provided. The inner layer includes a polymer and has an interior surface and an exterior surface. The interior surface has an Ra not greater than about 50 microns. The exterior surface is convoluted.

Abstract: The disclosure is directed to a fluid conduit including a hose and a fitting. The hose has a terminal end having a first portion along which an outer layer is laminated to an inner layer and a second portion along which the inner layer extends from the outer layer. The fitting includes a receiving portion and a coupling portion. The receiving portion has a first inner surface defining a first lumen portion, and is configured to receive the first portion of the terminal end, and for crimping to the hose. The coupling portion has a second inner surface defining a second lumen portion for receiving the second portion of the terminal end. The first lumen portion and the second lumen portion are in fluid communication with each other.
