Continental OE Technology Series HY-T Black Heater Hoses
Avoid a potential mishap from a leaking or a blown heater hose--make an upgrade to Continental OE Technology Series HY-T black heater hoses. The HY-Ts are perfect for applications where excellent resistance to antifreeze coolants and extreme underhood temperatures is required. The tube and cover are manufactured from EPDM (ethylene propylene diene monomer) rubber with superior resistance to heat, ozone, and chemical coolants. Each hose is then reinforced with 2-spiral synthetic for additional strength and durability. Continental OE Technology Series HY-T black heater hoses are constructed to meet specifications similar to SAE J20R3--so they can take the heat.
