Gates 18088 Small I.D. Molded Heater Hose

The Gates 18088 is a factory-molded, small inside diameter (I.D.) coolant hose designed to fit today's compact, tighter-fitting engine compartments. This OEM-style heater hose is precision-manufactured to provide reliable coolant transfer in applications requiring smaller diameter hoses, typically ranging from 1/4" to 1" inside diameter.

Key Features:

• Constructed with EPDM tube, synthetic fiber knit reinforcement, and EPDM cover for maximum durability
• Engineered to resist electrochemical degradation (ECD), the leading cause of hose failure
• Operates within an impressive temperature range: -40°F to +275°F (-40°C to +135°C)
• Meets SAE 20R3 EC Class D-1 and D-2 specifications
• Approved for coolant, water, and air applications, including marine use
• Resists water permeation to reduce coolant loss through the hose wall
• Factory-molded to OEM specifications for proper fit and performance

Gates recommends replacing hose clamps each time a new coolant hose is installed for optimal sealing and leak prevention. This hose is not suitable for fuel or oil transfer applications. Ideal for automotive heating and cooling system repairs where space is limited and OEM-quality replacement parts are essential.
