Continental Contitech 20017178 Straight Radiator Hose

Product Description

The CONTINENTAL CONTITECH 20017178 is a straight radiator hose constructed from Versgard EPDM, designed for heavy-duty cooling system service. Measuring 3 feet in length with a 3.5-inch inner diameter, it handles working pressures up to 150 psi and temperatures up to 300 degrees F. The EPDM compound resists coolant degradation, ozone, and heat cycling, making it well suited for high-demand engine cooling applications. The blue color provides quick visual identification during service. This hose is intended for installation by qualified diesel mechanics, fleet technicians, and heavy equipment service professionals.

This hose is used in large-bore cooling system applications where a straight, unrestricted flow path is required. Typical installations include heavy-duty trucks, construction equipment, agricultural machinery, and industrial engines with larger radiator inlet and outlet connections. Its straight configuration suits installations where routing does not require a molded or pre-bent shape. Technicians working on vehicles or equipment with 3.5-inch cooling system ports will find this a direct-fit solution for replacement or new-build plumbing.

Installation Notes

Installation should be performed by a qualified mechanic or fleet service technician. Drain and depressurize the cooling system completely before removing any hose. Inspect clamp seats and radiator fittings for corrosion or damage before fitting the new hose. Follow equipment manufacturer torque specifications for hose clamps and refill the system with the correct coolant type before returning the unit to service.
