Abstract: A leak-free flexible conduit and method ofmaking the same is described. By attaching a flexible outer hose (14) to a flexible inner hose (12) without directly clamping the outer hose to the inner hose, the life of the inner hose is increased. Furthermore, the outer flexible hose creates a heat-resistant, airtight seal (22a) that prevents exhaust leaks from the inner flexible hose from escaping, substantially reduces the heat lost to the atmosphere, decreases the amount of vibration, reduces noise, and protects the inner flexible hose from corrosive elements and contaminants, thereby also extending the life of the inner flexible hose.
