Dayco Radiator Coolant Hose 71421
Flexible hose that is part of the engine cooling system. (71421) by Dayco
Dayco ® Molded Radiator and By-Pass Hose with knitted reinforcement and all synthetic EPDM rubber construction provides the high strength and resistance to oil, mud, salt, road debris, ozone, coolants, and temperature variations of -40 °F (-40 °C) to +257 °F (+125 °C) that are required for OEM hose replacements. The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose. In addition to meeting SAE J20R4, Class D-1 requirements, this hose is now designed to meet Type EC electro-chemical requirements as specified in SAE J1684; which prevents inner tube deterioration caused by the build up of static electric charges.
