Key Features:

• Molded EPDM rubber construction resists electrochemical degradation and collapse under vacuum
• 27-3/8 inch centerline length with dual diameter ends: 11/16 inch (17mm) and 7/8 inch (22mm)
• Integrated quick-connect fitting for secure, leak-free connections
• Temperature range: -40°F to +257°F (-40°C to +125°C)
• Meets SAE 20R3 EC Class D1 and SAE 20R4 EC Class D1 standards
• Reinforced with steel and plastic components for durability

Gates modular coolant hoses are manufactured to OE specifications and include essential integrated components such as branches, quick-connectors, sensors, and restrictors. The specifically-engineered materials resist collapse under vacuum and are designed to combat electrochemical degradation, the leading cause of coolant hose failure. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal performance.
