Pressurized air travels through the hose whenever braking commands are issued, moving from control valves toward brake actuators. The hose accommodates suspension movement while maintaining a sealed airflow path. Pressure changes inside the hose occur in response to braking input without manual adjustment. Airflow starts and stops as the brake system cycles. The Mack 22198856 connects braking components through flexible pneumatic routing.
