Gates 12130 Molded Heater Hose

The Gates 12130 is a premium molded heater hose engineered to deliver reliable coolant flow in automotive heating and cooling systems. Precision-shaped to OEM specifications, this hose is designed to fit the contours of your engine compartment for a leak-free, secure connection right out of the box.

Gates molded coolant hoses are constructed with an EPDM rubber tube and cover with synthetic fiber knit reinforcement, providing outstanding resistance to heat, ozone, and chemical coolants. The EPDM compound is specifically formulated to combat electrochemical degradation (ECD) — the leading cause of coolant hose failure — so you can count on long-lasting performance.

Key Features:

• Pre-molded, OEM-style shape for direct-fit installation
• EPDM tube and cover for superior heat and ozone resistance
• Synthetic fiber reinforcement resists vacuum collapse
• Engineered to resist electrochemical degradation (ECD)
• Meets SAE 20R4 EC Class D1 requirements
• Temperature range: -40°F to +275°F (-40°C to +135°C)
• Approved for automotive heater and coolant circuit applications

Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure a proper, lasting seal. The Gates 12130 is a trusted OEM-quality replacement that saves time and cost compared to dealer sourcing.
