Four Seasons Hose Assembly Product Line Details

The Hose Assembly product line from Four Seasons focuses on delivering precise HVAC hose and pipe solutions tailored to specific vehicle applications. This line emphasizes quality materials and exact fitment, providing assemblies that integrate essential components such as service ports and seals. The 56390 hose assembly exemplifies this approach by combining aluminum and rubber construction with included O-rings and gaskets to maintain system integrity in Ford and Mercury A/C systems.

Technical Description and Features

This hose assembly serves as both the discharge and suction line for A/C refrigerant flow. The discharge end utilizes a P-nut fitting style, while the suction end features a 0.625 inch (15.875 mm) male springlock block type connection. The assembly includes a manifold and a service port with an R134a quick disconnect, facilitating maintenance and refrigerant charging. Although fittings are not included, the package contains multiple green O-rings (part numbers 24628 and 24670) and a spring O-ring (part number 24220) to ensure leak-free connections. The assembly does not include a bracket or muffler, aligning with original equipment design.

Applications and Common Issues Addressed

  • Replacement of worn or leaking A/C refrigerant hoses in Ford Contour, Mercury Cougar, and Mystique
  • Restoring proper refrigerant flow and pressure in R134a systems
  • Resolving issues related to damaged or missing O-rings and gaskets causing leaks
  • Addressing service port failures or incompatibility with quick disconnect tools
  • Repairing assemblies lacking proper manifold or fitting connections

Installation Notes and Tips

Ensure the vehicle’s A/C system is fully evacuated before removing the old hose assembly. Verify compatibility with the Ford Contour, Mercury Cougar, or Mystique models prior to installation. Use the included green O-rings and gaskets to replace any worn seals, preventing refrigerant leaks. The P-nut fitting and male springlock connections require proper torque specifications to maintain system integrity. Since fittings and switches are not included, confirm these components are in good condition or replaced separately as needed.
