Move refrigerant back to the compressor and keep your air conditioning cycling with the Four Seasons A/C Refrigerant Suction Hose 65978. This suction line hose assembly drops in as a direct-fit replacement for the 2016-2022 Lexus RX450H and the 2018-2022 Lexus RX450HL; see the Buyer's Guide tab for the engine-level applications.

  • Double-wall barrier hose: constructed with double-wall barrier hose compatible with R1234YF, R134A, or R12 refrigerant.
  • Includes sealing hardware: comes with the gaskets, o-rings, or seals needed to properly replace the product.
  • Crimp fitting connection: uses a crimped fitting connection.
  • Application-specific design: designed specifically for the listed applications to route the low-pressure suction line.

The suction hose carries low-pressure refrigerant vapor from the evaporator back to the compressor inlet. If the original hose is leaking, chafed, or has failed at a crimp fitting, this assembly provides a sealed low-pressure path in the A/C system. Backed by Four Seasons' decades of mobile A/C experience.
