Air Brake Coil Hose

Air Brake Coil Hose

The Air Brake Coil Hose is specially developed for commercial vehicle pneumatic braking applications requiring durability, flexibility, and reliable air flow performance. Made from imported PA6 and PA12 raw materials, the hose features a smooth inner surface that reduces airflow resistance and improves braking response. Its spiral structure allows compact installation while maintaining excellent extension and recovery performance during vehicle movement.

Vehicle & Electrical Applications 

Air Brake Coil Hose is widely used in tractor trucks, semi-trailers, trailers, commercial vehicles, and pneumatic braking systems for reliable pipeline connections between towing and braking components.

In addition, nylon-protected seven-core electrical coils are commonly used for electrical connections between prime movers and trailers. The flexible nylon tube structure keeps the cable coil compact, neat, and resistant to external damage, improving both appearance and service reliability in vehicle connection systems.
