BC Transit – Air Brake Course 3. Five Main Components: b) Air Lines 38
Air Lines • Air lines link compressed air from one component to another. • Air flowing from the Compressor moves down the Air Line or main discharge line to the wet tank. • Air lines are made of a durable, tensile material – they can withstand pressure of at least 150 PSI. • Application air lines (also known as service or control lines) have a narrow diameter – Supply air lines (also known as delivery lines) have a larger diameter. 39
