ABSTRACT:
A twin tube air brake hose for delivering compressed air to brakes on a vehicle such as a truck includes a first tube which serves as a service tube and a second tube which serves as an emergency tube. The first tube and second tube have an inner layer surrounded by a reinforcing layer which is in turn surrounded by an outer rubber layer. The outer rubber layers of each tube are joined by a web which is unitary with the outer layers. Adjacent opposite ends of the twin tube brake hose, the tubes are separated to form free end portions, each of which have a metal fitting. Reinforcing bands are fitted around the twin tube air brake hose just inboard the tail ends to prevent the web from splitting.
