Railway passenger car air brake hose assembly train air hose coupling train parts accessories
Railway air brake hose coupling are provided to connect brake pipeline and feed pipeline/MR MR pipeline throughout the train.the coupling heads the feed pipe/MR coupling hose are of opposite design to those of the brake pipe coupling hoses. For installation of the air brake hose coupling ,they are provided with threaded nipples on one end of the hoses,these nipples are screwed on /into the angle cock at the both ends for the wagons.

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.
Application
Railway vehicles
Railway wagon
Railway locomotive
