Keep cool, low-pressure refrigerant vapor moving from the evaporator back to the compressor with the Four Seasons A/C Refrigerant Suction Hose (MPN 66843). It's an application-specific, direct-fit replacement for the 2007-2017 Toyota Tundra — see the Buyer's Guide tab for engine-level coverage.
This suction line assembly carries refrigerant on the low-pressure side of the A/C loop. When the original hose cracks, chafes, or leaks at a fitting, refrigerant escapes and cooling performance drops; if a failed suction hose is the cause, this replaces it.
- Double-wall barrier hose: constructed to be compatible with R1234YF, R134A, or R12 refrigerant systems.
- Crimp fitting connections: uses crimped end fittings.
- Seals included: contains gaskets, o-rings, or seals to properly complete the replacement.
- Application-specific design: engineered for the listed application, backed by over 50 years of Four Seasons mobile A/C experience.
Recover the refrigerant and depressurize the system before servicing, and evacuate and recharge to the correct specification after installation.
