Dayco 87806 Molded EPDM Heater Hose

The Dayco 87806 is a precision-molded heater hose engineered to replace OEM coolant hoses in applications requiring small diameter hose (1-inch inner diameter or smaller). This hose maintains proper coolant circulation between the engine and heater core for reliable climate control performance.

Construction and Materials:

• Synthetic EPDM (ethylene propylene diene monomer) rubber construction for superior durability
• Knitted rayon reinforcement in the inner base tube provides maximum strength and burst resistance
• Molded configuration eliminates the need for multiple hose connections and clamps
• Temperature range: -40°F to +257°F (-40°C to +125°C)

Performance Features:

• High resistance to oil, salt, mud, debris, coolants, and environmental elements
• Meets SAE J20R4, Class D-1 specifications
• Designed to meet Type EC electro-chemical requirements per SAE J1684
• Application-specific molded design ensures proper fit and function

This direct OEM replacement hose is manufactured to meet the highest standards required for original equipment replacements. Regularly inspect cooling system hoses and replace at the first signs of cracking, sponginess, or wear to prevent coolant leaks and maintain heating system performance.
