Considering this DOT-approved tube is 90% copper and 10% nickel, it bends relatively easily. Its flexibility means you can pull this hose through tight and awkward spots in your car like you're towing a Romex around your home. You can easily bend larger radii, softer bends around objects, but if you're making tighter bends on the order of 3 inches in radius or less, I recommend a bending tool or some sort of mandrel to prevent the tube from twisting or twisting Break for smaller radius bends. .
