Gates 12482 Premium Molded Heater Hose

The Gates 12482 is a Premium Molded Heater Hose from Gates' Small I.D. molded coolant hose line. Factory-molded to OEM specifications, this hose is engineered to fit today's smaller, tighter engine compartments with precision and reliability.

Gates molded heater hoses are built with an EPDM tube, synthetic fiber reinforcement, and EPDM cover, delivering exceptional resistance to electrochemical degradation (ECD) — the leading cause of hose failure. ECD occurs when the hose, coolant, and metal fittings interact to form a galvanic cell, causing micro-cracks and eventual hose failure. Gates' advanced EPDM construction combats this process for long-lasting, leak-free performance.

Key Features:

• Factory-molded OEM-style design for precise, drop-in fitment
• EPDM tube and cover with synthetic fiber reinforcement
• Engineered to resist electrochemical degradation (ECD)
• Resists water permeation for a secure, sealed connection
• Suitable for coolant, water, and air applications
• Approved for marine applications
• Operating temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 Type EC Class D-1 and D-2 specifications
• Caution: Not for use in fuel or oil transfer applications

Gates precision-manufactures this molded heater hose using exclusively developed factory processes to ensure compatibility and performance to OEM specifications, making it a direct, confidence-inspiring replacement for worn or failing heater hoses.
