Restore the low-pressure side of your air conditioning circuit with the Four Seasons A/C Refrigerant Suction Hose 66704, a direct-fit replacement for the 2016-2022 Volkswagen Passat (see the Buyer's Guide tab for the engine-level applications). This suction line assembly routes low-pressure refrigerant vapor from the evaporator back to the compressor; a cracked, chafed, or leaking original hose lets refrigerant escape and can leave the system undercharged and blowing warm. If a failed suction hose is the source of your A/C leak, this assembly replaces it.

  • Ready to seal: contains the gaskets, o-rings, or seals needed to properly replace the product.
  • Barrier construction: built with double-wall barrier hose compatible with R-1234yf, R-134a, or R-12.
  • Crimp fitting connection: crimped end fittings.
  • Application-specific design: engineered for the listed vehicle.

Backed by more than 50 years of mobile A/C experience from Four Seasons, this hose is engineered and tested for years of trouble-free operation. Have the system evacuated and recharged to the correct specification after installation.
