Gates 51719 Molded Modular Coolant Hose

The Gates 51719 is a molded modular coolant hose engineered to OEM specifications for specific vehicle applications, featuring integrated components such as hose branches, quick-connectors, sensors, or restrictors as required. This precision-molded hose is constructed with specifically-engineered materials that resist collapse under vacuum conditions.

Key Features:

• Engineered to resist electrochemical degradation, the leading cause of coolant hose failure
• EPDM tube construction with synthetic fiber knit reinforcement and heat-resistant EPDM cover
• Operating temperature range from -40°F to +257°F (-40°C to +125°C)
• Meets SAE 20R3 EC Class D1 standards for hoses under 1-inch ID, and SAE 20R4 EC Class D1 for 1-inch ID and over
• Heat and ozone resistant cover for extended service life
• Pre-shaped to ensure proper fit and perfectly sealed connections

Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing performance. Caution: Do not use this hose for fuel or oil transfer applications.
