Route refrigerant through the A/C system and shed cabin-cooling heat with the Four Seasons A/C Suction and Liquid Line Hose Assembly 66969, an internal heat-exchange (IHX) line that installs as a direct-fit replacement for the 2019-2020 Kia Optima with the L4-2.0L or L4-2.4L engine.

  • Double-wall barrier hose: compatible with R1234YF, R134A, or R12 refrigerant.
  • Crimp fitting connection: P-Nut fittings on both ends (End 1 and End 2).
  • Ready to install: includes gaskets, o-rings, or seals, plus fittings and a service port; built with an internal heat exchanger and a muffler. Sold without a bracket.
  • Application-specific design: aluminum and rubber construction, cataloged refrigerant type R1234YF.

Backed by over 50 years of Four Seasons mobile A/C experience, this combined suction-and-liquid line carries low-side vapor back to the compressor while delivering high-side liquid to the evaporator. If a cracked, chafed, or leaking factory line is the cause of weak cooling or lost refrigerant charge, this assembly replaces it. Diagnose the cause before replacing.
