This 1/2" Rubber Air Brake Hose is made specifically for air brake systems of trucks, trailers, and buses. The air brake hose has a smooth interior that allows for optimal airflow and reduced pressure drop, which helps to prevent brake failure, enhancing the overall performance of the brake system. The hose is also designed with a reinforced braided steel wire that prevents it from kinking or collapsing under pressure. This hose not only meets SAE J1402A requirements, but ensures the heavy duty resistance you need in an air brake hose. FleetPride is your First Click in Heavy Duty®.
