What is the purpose of air line fittings in the brake system?

The purpose of air line fittings in the brake system is to connect various components of the air brake system. These fittings are crucial because they ensure that air can flow between components such as the air compressor, air tanks, brake valves, and brake chambers. This connection is vital for the proper functioning of the air brake system, as it allows the pressurized air to be effectively routed throughout the system to activate the brakes when needed.

Since the air brake system relies on a seamless flow of air to create the necessary pressure for braking, the integrity and reliability of these fittings play an essential role. If the fittings are not secure or if there are leaks, it can lead to a decrease in braking performance and possibly even a failure to stop the vehicle safely. Therefore, proper connections facilitated by the air line fittings are fundamental to ensuring the safety and efficiency of the braking process.
