About the Four Seasons Hose Assembly Product Line

The Four Seasons Hose Assembly line focuses on providing high-quality HVAC hoses and pipes that meet or exceed original equipment standards.

The 56431 hose assembly is part of this line, offering a reliable solution for A/C refrigerant discharge and suction needs without compromising system integrity.

Detailed Product Description

This hose assembly combines aluminum and rubber components to withstand the pressures and temperatures typical in automotive air conditioning systems. It is specifically designed for use with R134a refrigerant, the standard for many modern vehicles. The assembly includes multiple O-rings—one slimline washer (24402), two sealing washers (24354), and one additional slimline washer (24404)—to ensure leak-free connections. Both the discharge and suction ends utilize P-nut fittings, facilitating secure attachment to the vehicle's HVAC system. The inclusion of a service port with a quick disconnect feature allows for easier system servicing and refrigerant handling. While the assembly comes with a manifold, it does not include fittings, brackets, mufflers, or switches, so those components must be sourced separately if needed.
