SAE J20R1 Blue Silicone Radiator Hose, 2-3/8"

SAE J20R1 Blue Silicone Radiator Hose, 2-3/8"

The RADIATOR-2-3/8 SAE J20R1 Blue Silicone Radiator Hose is a heavy-duty coolant hose built for demanding cooling systems, including turbo-diesel applications. Rated for 70 PSI max working pressure with a 210 PSI minimum burst pressure, it’s designed to handle the pressure and heat swings of radiator and coolant lines while keeping flow where it belongs—inside the hose, not decorating the engine bay in modern art.
