Description
Coupling heads connect the compressed-air brake lines between a towing vehicle and its trailer. The head seals the line when the vehicles are uncoupled, so the circuit holds pressure and the service and supply lines stay separated. The colour of the cap follows the usual convention: yellow for the control (service) line, red for the supply (emergency) line.
