Detailed Product Description

The Four Seasons 55797 hose assembly combines aluminum and rubber to provide a balance of strength and flexibility necessary for A/C refrigerant discharge and suction lines. It is designed for use with R134a refrigerant, the standard for many late-model vehicles. The assembly includes three green o-rings to ensure leak-free connections at critical junctions. The discharge and suction ends both feature female o-ring fittings with UNF threads, facilitating a secure and proper fit. Additionally, the included muffler and manifold help reduce noise and improve system operation. While the assembly includes a switch service port, fittings and brackets are not included, so installation may require reuse of existing hardware or separate purchase.
