Keep low-pressure refrigerant vapor flowing back to the compressor with the Four Seasons A/C Refrigerant Suction Hose (P/N 66778), an application-specific suction line hose assembly that drops in as a direct-fit replacement for the 2000-2002 Hyundai Accent. This is the large-diameter line that carries cool, low-pressure refrigerant from the evaporator back to the compressor; cracked, chafed, or leaking hose and fittings are common signs it may need replacing.

  • Double-wall barrier hose: constructed with double-wall barrier hose compatible with R1234YF, R134A, or R12 refrigerant.
  • Crimp fitting connection: crimped end fittings for a secure connection to the system.
  • Seals included: contains gaskets, o-rings, or seals to properly replace the product.
  • Application-specific design: engineered and tested for years of trouble-free operation, backed by Four Seasons' 50-plus years of mobile A/C experience.

Evacuate and recharge the system to the specified refrigerant and oil per the vehicle service information after installation. Fits the 2000-2002 Hyundai Accent — see the Buyer's Guide tab for full engine-level fitment.
