摘要:
A hose having an asymmetrical cross-section but which exhibits symmetrical bending and crush resistance regardless of the direction of the bending and/or crushing forces exerted on the tube. The tube includes an outer wall and an inner strengthening rib which is coextruded with the outer wall, the inner rib fabricated from a material having a durometer which is at least equal to, or higher, i.e., equal or higher resistance to deflection and/or indentation, than the material out of which the outer wall is fabricated.
