Four Seasons Hose Assembly Product Line Details

The Hose Assembly product line by Four Seasons focuses on delivering precise HVAC hose and pipe solutions tailored to specific vehicle applications. This line emphasizes quality materials and exact fitment, such as the 55450 hose assembly, which integrates essential components like O-rings and switch ports to maintain system integrity and performance in compatible Buick, Chevrolet, Oldsmobile, and Pontiac vehicles.

Detailed Product Description

The Four Seasons 55450 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 to work with R134a refrigerant, the standard for many automotive air conditioning systems. The assembly includes green O-rings ([24606] and [24612]) to ensure leak-free connections at both discharge and suction ends, which feature female UNF O-ring fittings. A built-in muffler reduces operational noise, while the manifold supports system integration. The included switch service port allows for easy system diagnostics and maintenance. This hose assembly does not include fittings or brackets, so those components must be sourced separately if needed.

Common Applications and Issues Addressed

• Replacement of worn or damaged A/C refrigerant discharge and suction hoses
• Resolving refrigerant leaks caused by degraded O-rings or hose material
• Addressing noise issues in the HVAC system with the integrated muffler
