Four Seasons 55613 Liquid Line Hose Assembly

The Four Seasons 55613 Liquid Line Hose Assembly is a critical replacement component designed for automotive air conditioning systems to facilitate the efficient transfer of high-pressure liquid refrigerant. Manufactured by Four Seasons, a recognized supplier in the heating, ventilation, and air conditioning (HVAC) aftermarket category, this hose serves as a durable conduit that maintains system pressure between the condenser and the expansion valve or accumulator tank.

Specifically engineered to withstand the thermal cycles and vibrations inherent to moving vehicles, the assembly utilizes reinforced construction to resist cracking, swelling, or leaking over time. As an integral fluid transfer line, this hose ensures that the liquid refrigerant remains contained within the closed loop necessary for heat exchange and cooling production. Failure to maintain seal integrity on this specific line results in significant refrigerant loss, reduced cooling capacity, and potential environmental release of the gas compound.

Installation of this unit requires attention to proper torque values and routing specifications to avoid kinks that restrict flow or cause premature fatigue. The design prioritizes compatibility with existing fittings for straightforward integration into service repairs, helping restore original factory performance metrics. For technicians managing climate control maintenance, selecting verified components like the 55613 helps ensure the longevity of the entire A/C circuit.
