Railway air brake hose assembly with UIC standard vehicles brake hose coupling
Brake coupling head
components that when mechanically coupled together allow a flow of pressurised air between them.
Nipple
Component at one end of the pneumatic half coupling that connects it to the end cock, or pipe, located on the vehicle.
Hose clip
Component that mechanically fixes the hose to the coupling head or the nipple in order to assembly the pneumatic half coupling.
Sealing washer
Component that is installed in the coupling head to prevent unacceptable loss of air when two coupling heads are connected to one another.
Hose
Component that is connected between the brake coupling head and the nipple to convey the pressurised air and give the required flexibility between vehicles, and that is generally made up of a elastomeric tube, textile reinforcement and a elastomeric covering bonded together.
Tube
Interior layer of the flexible hose.
Reinforcement
Intermediate layer that provides the strength to maintain the general shape of the hose whilst giving the flexibility.
Covering
External layer of the flexible hose which protects the interior constituents from mechanical and environmental damage.
