Four Seasons Hose Assembly Product Line Details

The Four Seasons Hose Assembly product line focuses on providing complete hose assemblies for automotive HVAC systems. These assemblies combine suction and liquid line hoses with integrated fittings, seals, and service ports to facilitate efficient refrigerant flow and system servicing. The 66974 model exemplifies this approach by including essential components such as O-rings and a muffler to reduce noise and maintain system integrity.

Detailed Product Description

This hose assembly is engineered for Hyundai Elantra vehicles using R134a refrigerant. Both ends feature P-nut fittings, ensuring a secure and leak-resistant connection to the A/C system. The assembly includes a service port and multiple O-rings (part numbers 24622, 24109, and 24629) to maintain a tight seal and prevent refrigerant loss. The aluminum and rubber materials provide a balance of strength and flexibility, while the integrated muffler helps reduce operational noise. This hose assembly is supplied without a mounting bracket, allowing for compatibility with existing vehicle hardware.

Common Applications and Issues Addressed

  • Replacement of worn or damaged A/C suction and liquid line hoses on Hyundai Elantra
  • Resolution of refrigerant leaks caused by degraded seals or fittings
  • Elimination of A/C system noise through the included muffler
  • Restoration of proper refrigerant flow for efficient cooling performance
  • Facilitation of maintenance with the integrated service port

Installation Notes and Tips

When installing the Four Seasons Hose Assembly 66974, ensure all O-rings are properly seated to prevent leaks. The P-nut fittings require careful tightening to manufacturer torque specifications. Since this assembly does not include a bracket, verify that existing mounting points are secure and undamaged. Use appropriate refrigerant handling procedures when connecting to the R134a system and check for leaks after installation.
