Four Seasons A/C Refrigerant Discharge Hose P/N:66831
Four Seasons A/C Refrigerant Discharge Hose P/N:66831
$43.99

Route high-pressure refrigerant from the compressor to the condenser with the Four Seasons A/C Refrigerant Discharge Hose 66831, a direct-fit replacement for the 2013-2016 Mazda CX-5. This discharge line assembly carries hot, high-side refrigerant on its way to the condenser, and a cracked, leaking, or oil-fouled hose is a common reason an A/C system loses charge and stops cooling — if the discharge hose is the cause, this replaces it.

  • Application-specific design: built to match the routing and connections of the listed Mazda CX-5 applications.
  • Double-wall barrier hose: constructed to be compatible with R-1234yf, R-134a, or R-12 refrigerant.
  • Crimp fitting connection: uses factory-style crimped end fittings.
  • Seals included: contains the gaskets, o-rings, or seals needed to properly complete the replacement.

Backed by Four Seasons and over 50 years of mobile A/C experience. Always evacuate and recharge the system to the correct specification after installation, and diagnose the source of any leak before replacing parts.
