- 1st Air Pipe Assembly
- The air brake system begins with the 1st air pipe assembly. This crucial component includes the front mounting upper flat washer, which provides a stable surface for securing other components. The assembly also features a transition joint that connects different sections of the pipeline. The transition joint is bolted into place using nuts, ensuring a secure connection. A high-temperature hose assembly is also part of this section, designed to withstand the heat generated during braking.
- Connecting Components
- Following the 1st air pipe assembly, the diagram shows several critical components, including bolts and nuts that fasten the pipe assembly. The second air pipe assembly connects directly to the air compressor, facilitating the flow of compressed air through the system. The transition joint and the three-way pipe joint are essential for directing air to various parts of the system, allowing for flexible routing and connections.

- Pipe Clamps and Brackets
- To maintain the integrity of the pipeline, the system uses a series of clamps and brackets. These include lower and upper pipe clamps, which are fastened using bolts and nuts to keep the pipes securely mounted. Single clip upper and lower brackets are also used to provide additional support and stability. These components are essential for preventing movement and ensuring the correct alignment of the pipes.
- Elbow and T-Joints
- Elbow pipe joints and T-joints are critical for changing the direction of the airflow within the system. These joints are equipped with nuts and washers to ensure a tight and secure fit. Septa elbow pipe joints and T-joints are used for more complex configurations, allowing for multiple connections and directional changes within the pipeline.
- Air Ventilation and Nylon Pipe Assemblies
