Four Seasons A/C Refrigerant Discharge Hose P/N:66911
$39.99

Move hot, high-pressure refrigerant from the compressor to the condenser with the Four Seasons A/C Refrigerant Discharge Hose 66911, an application-specific replacement for the 2008-2015 Smart Fortwo (L3-1.0L). On the discharge (high-pressure) side of the A/C system, this line carries pressurized refrigerant gas leaving the compressor toward the condenser; a cracked, chafed, or leaking hose is a common sign this part may need replacing, often showing up as lost refrigerant and weak cooling.

  • Double-wall barrier hose: compatible with R1234YF, R134A, or R12 refrigerant.
  • Crimp fitting connection: aluminum and rubber construction for a secure sealed joint.
  • Application-specific design: shaped for the listed Smart Fortwo application.
  • Included to complete the job: contains gaskets, o-rings, or seals; service port included. No bracket; supplied without a muffler.

Backed by Four Seasons' decades of mobile A/C experience, this discharge line assembly is engineered and tested for dependable operation. If a leaking or damaged discharge hose is the cause of your A/C performance loss, this assembly replaces it.
