Trailer Air Brake Coil Hose Polymer Spiral Structure for Heavy Truck Semi

The Trailer Air Brake Coil Hose is the coiled air connection between a tractor unit and a semi-trailer, and it carries the compressed air that operates the trailer brakes. The hose is made of a high quality polymer material that gives it strong resilience, so it stretches freely as the vehicle turns and will not sag or drag on the ground when the combination is in motion.

The polymer material resists high and low temperatures, ozone and ultraviolet light, so the hose does not easily age or crack under long term outdoor use. It is pressure resistant and explosion proof, and it holds a stable air tightness that keeps the air supply to the trailer braking system smooth and reliable. The spiral structure prevents the hose from kinking during turning, which keeps the air flowing even at full lock.

The hose is equipped with colour coded connectors that prevent wrong connection and allow quick assembly, which speeds up coupling and uncoupling of the trailer and reduces the risk of a brake fault caused by crossed lines. The coil hose is suitable for all types of heavy trucks and semi-trailers, and it is the correct replacement for a hardened, cracked or leaking air line that can no longer keep the trailer brakes working reliably.

• Strong Resilience Polymer: The high quality polymer material gives the hose strong resilience, so it stretches freely and will not sag or drag on the ground.
• Temperature, Ozone and UV Resistant: Resistant to high and low temperature, ozone and UV rays, the hose does not easily age or crack under long term outdoor use.
• Pressure Resistant and Explosion Proof: The pressure resistant, explosion proof construction keeps a stable air tightness and ensures a smooth air supply to the trailer braking system.
• Spiral Anti Kink Structure: The spiral structure prevents the hose from kinking during turning, so the air keeps flowing even when the combination is at full lock.
• Colour Coded Connectors: Colour coded connectors avoid wrong connection and allow quick assembly, cutting coupling time and preventing brake faults from crossed lines.
• Universal Trailer Fitment: Suitable for all types of heavy trucks and semi-trailers, the coil hose is the direct replacement for a hardened or leaking air line.

The trailer air brake coil hose is used as the flexible air connection between a tractor unit and a semi-trailer, carrying the compressed air that operates the trailer brakes. It is the correct replacement for a hardened, cracked or leaking air line that can no longer keep the trailer brakes working reliably, and it is chosen by fleets, transport companies and repair workshops that need a durable, leak free air connection that survives daily coupling and uncoupling, long distance haulage and the stress of constant turning.

Each trailer air brake coil hose is packed in a neutral export carton with the model information on the label, so that the polymer coil and the colour coded connectors arrive free from damage and can be stored easily. OEM cartons and private labels are available on request. Every hose is produced to original equipment specification and inspected before shipment, and technical support and fitting advice are provided. Mixed containers and volume orders are welcome.
