Place of Origin:
China
Brand Name:
Tieke
Brief introduction:
Brake air hose coupling assembly is installed on end of locomotive and freight cars. It connects the brake air pipelines between locomotive and freight cars or between various freight cars, so that the locomotive could control the brake system of the whole marshal. It is an important part of the railway vehicle’s braking system.
The brake air hose coupling provided by Tieke has the features of high bursting strength, high bonding strength, excellent weather resistance and high pull-out strength. At present, it is widely used in various locomotive and vehicle manufacturing enterprises and railway vehicles maintenance units.
Brake air hose coupling assembly is mainly composed of threaded joint, ferrule, steel braided rubber hose, transition joint, coupling body, washer, etc.
