Brief Introduction

Air brake system plays a crucial role in heavy-duty vehicles on the road. Such as trucks and trailers. The normal operation of the system ensures a safe and effective stopping. As you can see in the picture above, the blue color hose, called service line, is used to carry air to the brakes. It is controlled by the foot brake on the trailer. The red one, called supply line or emergency line, is used to supply a steady stream of air to the air tanks. The tubes mentioned above are commonly made of nylon or PU material and are used to connect the front cab to the rear trailer. Besides, we also provide rubber air brake hoses which are installed near the tires. These rubber hoses can withstand high pressure compressed air and are more durable.
