Detailed Product Description

The Four Seasons 56417 hose assembly combines aluminum and rubber materials to provide a robust and flexible connection for the A/C refrigerant discharge and suction lines. It is specifically designed for use with R134a refrigerant, the standard for many modern vehicles. The assembly includes two types of O-rings—sealing washers (part number 24354) and slimline washers (part number 24403)—with two of each included to ensure leak-free sealing. Both the discharge and suction ends utilize P-nut fittings, facilitating secure attachment to the manifold and other HVAC components. This assembly also features a muffler to reduce operational noise and improve overall system comfort. While the assembly includes the necessary gaskets and seals, fittings and switches are not part of this kit, and the bracket is not included.

Applications and Common Issues Addressed

• Replacement of worn or damaged A/C refrigerant discharge and suction hoses
• Resolving refrigerant leaks caused by degraded seals or O-rings
• Eliminating noise issues in the HVAC system with the included muffler
• Restoring proper refrigerant flow in Chevrolet Silverado 2500 HD and GMC Sierra 3500 A/C systems
• Maintaining system integrity after manifold or hose damage

Installation Notes and Tips

When installing the Four Seasons Hose Assembly 56417, ensure all old seals and O-rings are removed and replaced with the included washers to prevent leaks. The P-nut fittings require proper torque to avoid damage or refrigerant loss. Since fittings and switches are not included, verify compatibility with existing components before installation. The assembly does not come with a bracket, so reuse the original or source a compatible bracket if necessary. Proper evacuation and recharge of the A/C system with R134a refrigerant should be performed following installation.
