Keep refrigerant moving through your Ford's air conditioning with the Four Seasons A/C Suction and Liquid Line Hose Assembly 66819. It's an application-specific, direct-fit replacement for the 2013-2019 Ford Explorer (V6-3.5L) that combines the suction line and liquid line into one assembly. The liquid line carries high-pressure refrigerant toward the evaporator while the suction line returns low-pressure vapor to the compressor, so a cracked, corroded, or leaking original can interrupt A/C performance if the line is the cause.

  • Double-wall barrier hose: built for durable refrigerant containment; cataloged for R134A systems.
  • Aluminum and rubber construction: aluminum lines and fittings paired with rubber hose, joined by crimp fitting connections.
  • P-Nut fitting ends: End 1 is a P-Nut fitting and End 2 is a Male P-Nut for the suction and liquid line connections.
  • Seals and fittings included: ships with the gaskets, o-rings, and sealing washers plus the required fittings, and a service port is included; supplied without a bracket and without a muffler.

Backed by Four Seasons' decades of mobile A/C experience, this is an application-specific, direct-fit replacement for the listed Explorer.
