Keep refrigerant moving from the condenser to the evaporator with the Four Seasons A/C Refrigerant Liquid Hose 65166. This liquid line hose assembly drops in as a direct-fit replacement for the 2012-2016 Tesla S — see the Buyer's Guide tab for the full application details. It carries high-pressure liquid refrigerant on the condenser-to-evaporator run, and a cracked, leaking, or corroded line is one possible reason a system loses charge and stops cooling.

Backed by Four Seasons' decades of mobile A/C experience, this hose offers:

  • Double-wall barrier hose: compatible with R-1234yf, R-134a or R-12 refrigerant.
  • Crimp fitting connection: the hose uses crimp fittings.
  • Seals included: contains the gaskets, o-rings, or seals needed to properly replace the product.
  • Application-specific design: designed for the listed application.

If a leaking or damaged liquid line is the cause of your A/C's lost charge, this assembly replaces it. Have the system evacuated and recharged to the correct refrigerant and capacity after installation.
