3 Ft. Silicone Coolant Hose with 4" Inside Dia., Blue

Silicone SAE J20R1 Class A radiator and coolant hose are rigid hoses used for routing mostly straight coolant and radiator lines in performance motors and vehicles, marine wet-exhaust systems, commercial truck and bus induction and cooling systems, agriculture and off-highway vehicles, and turbo-diesel vehicles. The hoses are convoluted inside and out and will not collapse under full vacuum. They are made from silicone, which provides excellent resistance to high temperatures, ozone, and UV rays. They also resist electrochemical degradation. These silicone hoses meet SAE (Society of Automotive Engineers) Standard J20R1 and have Class A high-temperature resistance.

Radiator and coolant hoses carry coolant from a vehicle's radiator to its engine to cool the engine and prevent overheating and vehicle malfunction. They also transport hot coolant from a vehicle's engine to its radiator, where the coolant is cooled for recirculation. Also known as antifreeze hoses, coolant lines, and coolant tubing, these hoses are made from materials that can withstand exposure to the chemicals and additives used in vehicle cooling systems.
