Gates 18148 Molded Heater Hose EPDM Coolant Hose - 90-Degree

The Gates 18148 Molded Heater Hose is a precision-engineered 90-degree molded heater hose designed as a direct OE replacement for heater core and coolant circuit connections. Manufactured by Gates, a global leader in fluid power and power transmission products, this hose delivers reliable, leak-free performance in demanding under-hood environments.

Key Features:

• EPDM Construction: Features an EPDM inner tube, synthetic fiber reinforcement, and EPDM outer cover for outstanding durability and heat resistance
• Electrochemical Degradation (ECD) Resistance: Engineered to resist ECD — the leading cause of premature hose failure — by preventing micro-cracking of the hose tube
• Water Permeation Resistance: Resists water permeation for a longer service life and consistent coolant flow
• Wide Temperature Range: Rated for operation from -40°F to +275°F (-40°C to +135°C), handling extreme under-hood heat and cold
• SAE Compliant: Meets SAE 20R3 EC Class D1 (under 1" ID) and SAE 20R4 EC Class D1 (1" ID and larger) standards
• 90-Degree Molded Design: Pre-shaped for sharp 90-degree bend applications, eliminating the need to force straight hose into tight corners
• Marine Approved: Suitable for use in marine cooling and heater applications in addition to automotive use
• Coolant and Water Compatible: Safe for use with coolant, water, and air applications; not intended for fuel or oil transfer

The Gates 18148 is molded to deliver a precise, factory-quality fit that eliminates coolant leaks and reduces installation time. Cross-reference part numbers include: 10148, 16070125, 18435L, 64635, 79730T0GA01, and 87952. Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing.
