Dayco Molded Radiator and By-Pass Hoses are designed to provide the high strength and resistance to oil, mud, salt, road debris, ozone, coolants, and temperature variations required for a superior performance replacement hose.

Product Features:
  • Made with synthetic EPDM rubber compounds that provide resistance to deterioration from ozone, coolants, and temperature variations of -40°F (-40°C) to +257°F (+125°C)
  • The inner base tube is reinforced with knitted rayon for maximum strength and burst resistance for the life of the hose
  • Meets SAE J20R4, Class D-1 requirements for improved service hose
  • Meets Type EC electro-chemical requirements as specified in SAE J1684; which eliminates premature deterioration of the inner tube caused by the build up of static electric charges
