Rubber Hoses

-EPDM Radiator Hoses

radiator hoses

Hebei Shida Seal Group specializes in the design and manufacture of radiator hoses, coolant hoses and heater hoses for a wide range of industries. All products and tooling is produced in our internal facility accredited to TS 16949 with full engineering, testing and CAD capability.

Radiator hoses can include wire support for vacuum resistance. Usually the rubber hoses have smooth surface.When the inside diameter of a hose is too large that the extruder can not extrude it, we usually manually wrap the hose with fabric, called wrapped hose.

We produce radiator hoses for original equipment manufacturers of passenger cars, SUV’s, heavy-duty trucks, buses, tractors, construction equipment, agricultural vehicles and engine / power generators.
