ABSTRACT:
An improved vacuum hose includes an axial vacuum conduit having outer linear buttresses integral with the conduit and arranged radially around the conduit; the buttresses are strengthened by substantially orthogonal ribs. Buttresses and ribs are imbedded in a matrix of flexible plastic which provides support and increases the collapse resistance of the conduit; the whole assembly is covered by a tough casing which may be a separate component or a treated surface of the matrix material.
