Product Details

Four Seasons Hose Assembly 65912 is part of the brand’s hose assembly line, focused on HVAC hose and pipe service components.

Common Problems This Part Can Address

  • Leaking A/C refrigerant line at the discharge or suction hose

  • Service port wear or sealing issues during HVAC maintenance
  • Restricted refrigerant flow caused by a failing line assembly
  • Noisy line operation where a muffler-equipped hose is required

Installation Notes

Verify the vehicle uses R1234YF refrigerant before installation. Inspect mating surfaces, replace worn seals as needed, and confirm the P-nut fittings align correctly with the original routing on the 2019 Chevrolet Corvette. Because fittings are not included, reuse or source the correct connection hardware as required by the vehicle application. Check the service port and switch service port details against the original part before final assembly.
