Detailed Description

This Four Seasons hose assembly is engineered as a discharge and suction line for vehicles equipped with R134a refrigerant. The design combines aluminum and rubber sections to match common HVAC routing needs, while the springlock and P-nut fitting ends support the specified connection style. Four Seasons 63173 is a practical replacement for Chevrolet Traverse and Chevrolet Traverse Limited models listed in the fitment data, and it cross-references UAC HA113883C for the same application.

The Hose Assembly product line focuses on application-specific A/C line service parts for refrigerant transfer and system sealing. Four Seasons 63173 follows that approach with included seal components, a service port, and a muffler to address the needs of the line assembly itself.

What It Is Used For

• Replacing a leaking or damaged A/C refrigerant hose assembly.
• Restoring refrigerant transfer in an R134a HVAC system.
• Addressing worn connection points at the springlock or P-nut ends.
• Correcting service port or seal-related A/C line issues.
• Repairing discharge and suction line routing in the HVAC circuit.

Installation Notes and Tips

Verify refrigerant type, end connections, and routing before installation. This part is listed for 2024 Chevrolet Traverse Limited and 2018-2023 Chevrolet Traverse applications with R134a. Confirm the existing line configuration matches the springlock and P-nut fitting design, and inspect mating surfaces before sealing the system.
