Key Features:

• EPDM tube construction with synthetic fiber knit reinforcement and EPDM cover for maximum durability
• Engineered with compounds that resist electrochemical degradation, the leading cause of coolant hose failure
• Re-engineered materials resist vacuum collapse, reducing the need for internal support springs
• Heat and ozone resistant cover for extended service life
• Operating temperature range: -40°C to +135°C (-40°F to +275°F)
• Meets SAE 20R3 EC Class D1 under 25mm (1") ID, SAE 20R4 EC Class D1 for 25mm (1") ID and over

This precision-molded hose is designed as a direct OEM replacement, providing a proper fit and reliable performance for your vehicle's cooling system. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing.
