Acme Automotive offers the GilaFlex inner-braided PVC air hose with a special blend of PVC that has no memory, so hose will lay flat on the ground. With a 180-degree bend radius, the hose will not kink and cut off air supply. A steel spring strain relief protects the hose at its weakest point, near the fitting, without inhibiting maneuverability. The smooth outer cover doesn't trap dirt and is easy to clean. The GilaFlex has a temperature range of -40 degrees F to 150 degrees F, and a working pressure of 325 psi at 70 degrees F.
