The assembly of the brake air hose coupling is located between either a locomotive and a freight car or between two freight cars. Its purpose is to link the brake air pipelines of railway vehicles, enabling the locomotive to manage the braking for the entire train. This component plays a crucial role in the braking system of railway vehicles.
Our brake air hose coupling boasts several advantages, such as high resistance to bursting, strong bonding capability, excellent durability against weather conditions, and impressive pull-out strength. Currently, it is extensively utilized in the manufacturing of locomotives, in various vehicle production companies, and in maintenance facilities for railway vehicles.
The main parts of the brake air hose coupling assembly include a threaded joint, a ferrule, a steel braided rubber hose, a transition joint, the coupling body, and a washer, among others.
