D.O.T. Certified–Safety Matters. Fluid Transfer Products, Inc. is a manufacturer of stainless steel braided Teflon® hoses. Like steel belted radial tires on your vehicle, steel-braided brake lines provide a similar improvement in safety. Unlike the factory-original rubber brake lines that came on your vehicle, stainless steel braided Teflon® brake lines don’t expand and contract under braking, stopping the vehicle with less brake pedal travel, without locking the brakes. Rubber brake lines become brittle over time and are prone to cracking and can be extremely dangerous.
