Gates 25680 Premium Molded Coolant Hose

The Gates 25680 Premium Molded Coolant Hose is a factory-molded, OEM-quality radiator and coolant hose engineered for precise fit and long-lasting performance. Designed as a direct replacement, this hose is pre-shaped to match original equipment specifications, making installation straightforward and ensuring a perfectly sealed connection every time.

Built with an EPDM tube and heat- and ozone-resistant EPDM cover reinforced with synthetic fiber knitting, the Gates 25680 is specifically engineered to resist electrochemical degradation (ECD) — the leading cause of coolant hose failure. The specially formulated materials also resist vacuum collapse, eliminating the need for internal support springs in most applications.

Key Features:

• Factory-molded for OEM-quality fit on upper, lower, bypass, heater, and other coolant circuit positions
• EPDM construction resists heat, ozone, and chemical coolants
• Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
• Specifically engineered materials resist vacuum collapse
• Temperature rated from -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R4 EC Class D1 specifications
• Approved for marine applications
• Pre-shaped for a perfectly sealed, leak-free installation

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a secure, long-lasting seal. The Gates 25680 is sold as a single hose.
