Gates 18143 Molded Heater Hose

The Gates 18143 Molded Heater Hose is a premium-quality coolant hose engineered for reliable performance in automotive heating and cooling systems. This pre-shaped molded hose is designed to provide a precise factory-quality fit, eliminating the need for extensive bending or modification during installation.

Construction and Materials:

• EPDM (ethylene propylene diene monomer) tube construction for superior coolant compatibility
• Synthetic fiber reinforcement provides strength and durability
• EPDM cover resists heat, ozone, and environmental degradation
• Engineered to resist electrochemical degradation (ECD), the leading cause of coolant hose failure
• Resists water permeation to maintain cooling system integrity

Performance Specifications:

• Operating temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 Type EC Class D-1 or D-2 specifications
• Compatible with most coolants and non-oil based coolant additives
• Approved for automotive, stationary engine, and marine applications

Installation and Compatibility: This molded hose couples to standard hose bead fittings and should be secured with proper hose clamps. Gates recommends replacing hose clamps each time a new coolant hose is installed to ensure leak-free connections. Suitable for air, water, and coolant applications.

Important: Do not use for fuel or oil transfer applications. Cross-references to OEM part number 10143.
