Keep high-pressure refrigerant moving from the compressor to the condenser with the Four Seasons A/C Refrigerant Discharge Hose 65966, a discharge line hose assembly that drops in as a direct-fit replacement for the 2016-2019 Lexus RX450H and 2018-2019 Lexus RX450HL. When the original discharge line cracks, chafes, or leaks at a crimped fitting, it bleeds off system charge and weakens cooling — this assembly provides a fresh sealed path on the high side.

  • Double-wall barrier hose: constructed to be compatible with R1234YF, R134A, or R12 refrigerants.
  • Sealing hardware included: contains the gaskets, o-rings, or seals needed to properly complete the replacement.
  • Crimp fitting connection: uses crimped end fittings for the line-to-component joints.
  • Application-specific design: engineered and tested for the listed vehicles, backed by Four Seasons' decades of mobile A/C experience.

Signs the original discharge hose may need replacing include an A/C system that won't hold charge, oily residue at the hose or fittings, or weak cooling from lost refrigerant. If a failed discharge line is the cause, this assembly replaces it. Have the system evacuated and recharged to the correct specification after installation.
