SAE J20 R3 R4 CLASS D1,D2, Radiator Coolant Hose specfication, Convoluted wire supported type. The SAE standard covers reinfored and flexible hoses intended for use in water and ethylene glycol based engine coolant system applications. EPDM, as the hose material, has excellent ozone and good heat aging resistance. The inner base tube is reinforced with knitted yarn for maximum strength and burst resistance for the life of the hose. Made with a protective sleeve that protects contact areas against abrasion and heat. The stainless steel spring instered is necessary under the negative working pressure.This construction of hose is designed for water and ethylene glycol based engine coolant system in engine of automotive, motorcycle, ATV, generator, general motor, construction machinery, Agriculture and forestry machinery, etc.
