EPDM (ethylene propylene diene monomer) SAE 20R3 class D2 heater hose can be cut to the desired size to allow users to connect a vehicle's engine to its heater core. This hose is commonly used to carry coolant between the engine and the heater core in cars and light trucks. This hose is made from EPDM, which provides excellent resistance to ozone and high temperatures and good resistance to chemicals. The hose meets SAE (Society of Automotive Engineers) standard 20R3 for class D2 hose. It is a normal-service heater hose with an inside diameter of 1" or less, and it provides low oil resistance.

Heater hoses carry coolant between a vehicle's engine and its heater core in order to warm up the vehicle's interior. They are a part of the vehicle's cooling system that keeps the engine from overheating and malfunctioning. These hoses are made from materials that can withstand exposure to the chemicals and additives used in vehicle cooling systems. These small-diameter hoses are reinforced with nylon cords to strengthen the hose.
