A hose having the shape of a hollow cylinder with definite wall thickness and outside diameter and indefinite length, which hose has a smooth surface and is constructed of extrudable polymer reinforced with discontinuous fibers wholly contained therein oriented so that the radial component of fiber orientation exceeds both the circumferential component of orientation and the axial component of orientation whereby the hose will swell, upon exposure to an organic solvent capable of swelling said polymer, in such a manner that the percent increase in its wall thickness is less than the percent increase in its outside diameter as a result of said swelling.
