High Performance 4826 AC Hose Type C Seven Layer Winding China Factory Suppliers
The 4826 A/C Hose (Type C) is a high-performance automotive air conditioning solution featuring an advanced seven-layer winding construction. Specifically engineered for the demanding environments of cars, trucks, and diverse commercial vehicles, this hose ensures maximum refrigerant containment and system efficiency. Its multi-layered architecture is designed to withstand extreme pressure fluctuations while maintaining optimal thermal stability.
Engineered for versatility and durability, this hose is fully compatible with industry-standard refrigerants including R134a, R404a, and the eco-friendly R1234yf. By integrating low permeability and high resistance to aging and ozone, KEMO provides a critical component that prevents leaks and extends the lifespan of the vehicle's HVAC system, ensuring consistent cooling performance under the harshest operating conditions.
