2. DESCRIPTION & FUNCTION  
--------------------------------------------------------------------------------  
The WG17017360470 air brake hose is a factory-original flexible connector designed for the pneumatic braking system in SINOTRUK HOWO trucks. It serves as a critical link between rigid air lines and moving components (e.g., axles, suspension systems), allowing uninterrupted transmission of compressed air under high pressure without leakage or structural fatigue.  
 
Constructed with multi-layer synthetic rubber compounds reinforced with braided polyester or steel wire, this hose ensures durability, resistance to abrasion, ozone, and extreme temperatures (-40°C to +120°C). The hose maintains consistent internal diameter performance to support rapid air response times essential for safe braking operations.

4. APPLICATION & FITMENT  
--------------------------------------------------------------------------------  
This genuine air brake hose is engineered exclusively for compatibility with SINOTRUK HOWO truck models, including but not limited to:  
• HOWO A7 Series  
• HOWO T7H Tractors  
• HOWO 6×4 & 8×4 Dump Trucks / Concrete Mixers  
• SINOTRUK Mining and Construction Variants  
 
It is typically installed in:  
- Axle-to-chassis air connections  
- Suspension-mounted brake chambers  
- Relay valve supply lines  
- Trailer gladhand coupling subsystems (when specified)
 
Note: Always verify fitment using VIN or chassis number through SINOTRUK’s official parts catalog (EPS system). Non-OEM hoses may compromise brake timing, increase chattering, or fail prematurely under load.
 
5. INSTALLATION, MAINTENANCE & SAFETY GUIDELINES  
--------------------------------------------------------------------------------  
• Installation:  
  - Use only OEM-approved fittings and clamps.  
  - Avoid twisting during installation; ensure straight alignment.  
  - Torque fittings to 25–30 Nm using calibrated tools.  
  - Conduct post-installation air leak test at 0.8 MPa for 5 minutes.  
 
• Maintenance:  
  - Inspect every 10,000 km or quarterly for cracks, bulges, abrasion, or leakage.  
  - Replace immediately if signs of aging, softening, or delamination appear.  
  - Lubrication: Never apply oil or solvent-based lubricants to the hose surface.  
 
• Safety Notice:  
  - A failed brake hose can result in partial or total loss of braking power.  
  - Only trained technicians should service pneumatic brake systems.  
  - Depressurize the entire air system before disassembly.
