The 4890 AC Hose is a high-performance automotive air conditioning conduit engineered for precision and durability. Specifically designed for cars, trucks, and heavy-duty vehicles, this hose ensures optimal refrigerant flow within the AC system while maintaining structural integrity under extreme thermal and pressure conditions.
Built to withstand the rigorous demands of modern automotive environments, our AC hoses feature advanced resistance to ozone, aging, and shock. By combining low permeability with high pulse resistance, KEMO delivers a reliable solution that prevents refrigerant loss and extends the lifespan of the vehicle's cooling system.
