Trailer Air Hose WG9000360140 Sinotruk 

Product Introduction

This Trailer Air Hose WG9000360140 is an OEM heavy-duty coiled air brake hose, specifically designed for Sinotruk heavy-duty trucks and commercial vehicle trailer combinations. Constructed from high-grade, oil-resistant rubber with a reinforced internal structure, it delivers reliable, consistent air pressure transmission under heavy-load, long-haul, and harsh operating conditions.

Performance

• High-Grade Rubber Construction: The heavy-duty, oil-resistant rubber compound provides exceptional durability and resistance to abrasion, ozone, and weathering, extending service life in all environments.

• Reinforced Internal Structure: The multi-ply, fabric-reinforced design ensures burst resistance and maintains consistent air pressure transmission, even under repeated flexing and pressure fluctuations.

• Coiled Design: The coiled structure provides flexibility and self-retraction, preventing tangling and damage during vehicle articulation and trailer coupling/uncoupling.

• Precision-Machined Fittings: The zinc-plated steel fittings ensure a secure, leak-proof connection to the vehicle’s air brake system, with a red protective cap to prevent contamination during storage.

• OEM Exact Fit: Optimized for Sinotruk heavy-duty truck models, it matches original length, coil diameter, and fitting specifications for seamless installation.

Core Function

1. Transmits compressed air pressure from the tractor to the trailer’s air brake system, enabling reliable brake actuation and control—a core part of heavy duty truck brake parts.

2. Provides flexibility and self-retraction to accommodate vehicle articulation and trailer movement, preventing damage and ensuring consistent performance.

3. Withstands repeated flexing and pressure fluctuations, maintaining reliable air pressure transmission over millions of coupling/uncoupling cycles.
