Continental Contitech 20017182 Straight Radiator Hose

Product Description

The CONTINENTAL CONTITECH 20017182 is a straight radiator hose designed for heavy-duty cooling system service. Built from Versgard EPDM compound, it handles coolant flow between the radiator and engine in demanding thermal environments. The hose measures 3 feet in length with a 4.5-inch inside diameter, making it suited for large-bore cooling circuits found in commercial vehicles, industrial equipment, and heavy equipment applications. It is rated to 150 psi maximum working pressure and withstands temperatures up to 300 degrees F. HVAC and fleet mechanics, as well as heavy equipment technicians, typically source this hose for high-volume cooling system rebuilds or replacements where OEM-specified dimensions must be matched closely.

This hose is appropriate for straight-run cooling system plumbing where a 4.5-inch bore and 3-foot straight length are required. Its blue EPDM construction resists coolant degradation, ozone, and heat cycling over extended service intervals. It is commonly used in radiator inlet and outlet runs on large diesel engines, industrial process cooling lines, and commercial vehicle cooling systems where high-pressure, high-temperature performance is a service requirement.

Compatibility

Designed as an OEM-style replacement straight radiator hose for large-bore cooling systems requiring a 4.5-inch inside diameter and 3-foot straight-run length at up to 150 psi working pressure.

Installation Notes

Installation should be performed by a qualified mechanic or equipment technician. Drain and safely dispose of coolant before removing the existing hose, and allow the engine to cool completely before beginning work. Use appropriately rated hose clamps torqued per the equipment manufacturer specifications, and inspect all mating fittings and clamp seats for corrosion or damage before installing the new hose. Verify the installed hose routing does not contact sharp edges, exhaust components, or moving parts.
