Gates 18619 Molded Heater Hose 90-Degree EPDM Replacement

The Gates 18619 Molded Heater Hose is a precision-engineered 90-degree pre-formed heater hose designed to simplify replacement in automotive assemblies that require sharp bends. Built to OEM specifications, this hose delivers a reliable, leak-free fit as a direct replacement for your vehicle's heating and cooling system.

Key Features:

• EPDM Construction: Features an EPDM inner tube, synthetic fiber reinforcement, and EPDM outer cover for long-lasting durability and flexibility
• Electrochemical Degradation Resistance: Engineered to resist electrochemical degradation (ECD) — the leading cause of heater hose failure
• Wide Temperature Range: Operates reliably from -40°F to +275°F (-40°C to +135°C) for year-round performance in extreme conditions
• SAE Certified: Meets SAE 20R3 EC Class D1 standards (for IDs under 1 inch) and SAE 20R4 EC Class D1 (for IDs 1 inch and larger)
• Water Permeation Resistance: Resists water permeation to maintain system integrity and prevent coolant loss
• Pre-Molded 90° Shape: Factory-molded bend eliminates the need to force straight hose into tight routing angles, ensuring proper fit and reduced installation time
• Compatible with Air and Water Applications: Suitable for coolant and air transfer — not for use with fuel or oil

Gates recommends replacing hose clamps each time a new heater hose is installed to ensure a secure, leak-free connection. As a globally trusted name in fluid power and power transmission, Gates engineers every hose to meet or exceed original equipment manufacturer specifications.
