Continental Contitech 20017239 Straight Radiator Hose

Product Description

The CONTINENTAL CONTITECH 20017239 is a straight radiator hose built for heavy-duty cooling system service. Constructed from Versgard EPDM, this hose handles coolant routing in demanding thermal environments, rated to 260 degrees F maximum and 150 psi maximum working pressure. At 3 feet long with a 4-inch inside diameter, it is sized for larger engine cooling applications where standard hose lengths fall short. The EPDM tube and cover construction resist coolant degradation, ozone, and heat cycling over extended service intervals. HVAC mechanics, heavy equipment techs, and fleet service professionals install this hose as a direct replacement in cooling systems requiring a full straight run.

This hose is suited for large-bore radiator and cooling system plumbing found in commercial vehicles, stationary engines, and industrial equipment. The straight configuration fits applications where no bend or elbow geometry is required between the radiator and engine block connections. The 4-inch inside diameter accommodates high-volume coolant flow typical of larger displacement engines or industrial cooling loops. The black EPDM construction is compatible with standard ethylene glycol-based coolant systems.

Key Features

• Versgard EPDM tube and cover resist heat, ozone, and coolant degradation
• Straight configuration for direct radiator-to-engine or plumbing runs
• 150 psi maximum working pressure for pressurized cooling systems
• 260 degrees F maximum temperature rating handles high-heat engine environments
• 4-inch inside diameter accommodates high-volume coolant flow
• 3-foot length provides generous material for custom-cut installations

Compatibility

Designed as an OEM-style replacement straight radiator hose for large-bore cooling systems requiring a 4-inch inside diameter and straight hose geometry.

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 fittings for corrosion or damage before fitting the new hose. Torque hose clamps to the vehicle or equipment manufacturer specifications and refill with the correct coolant mixture before returning the system to service.
