Four Seasons Expansion Valve Product Line Details

The Four Seasons Expansion Valve product line focuses on precision-engineered A/C flow restrictors that maintain proper refrigerant metering in automotive HVAC systems. The 39282 model exemplifies this line by offering a block type valve with captured o-ring fittings to prevent leaks and ensure consistent refrigerant flow, tailored for Lexus vehicles requiring R134a refrigerant.

Technical Description and Specifications

This A/C expansion valve features a block type design made from aluminum, providing corrosion resistance and durability. It includes two mounting holes for secure attachment. Both suction inlet and outlet fittings are female with No. 12 thread diameter but are not threaded, designed for a tight fit. The liquid inlet and outlet fittings are also female, with No. 6 and No. 10 thread diameters respectively, utilizing captured o-ring seals (green o-rings, part numbers 24611 and 24661) to prevent refrigerant leaks. The liquid inlet size measures 0.4 inches (10.2 mm), and the liquid outlet size is 0.61 inches (15.5 mm). This valve is engineered to meet or exceed OEM standards, ensuring compatibility and performance for Lexus LS460 and LS600h models.

Common Applications and Problem Solving

• Regulates refrigerant flow to maintain consistent A/C cooling efficiency
• Prevents refrigerant leaks with captured o-ring fittings
• Replaces faulty or worn expansion valves causing poor cooling or system pressure issues
• Addresses A/C system cycling or freezing problems related to expansion valve malfunction
• Ensures proper refrigerant metering for Lexus LS460 and LS600h air conditioning systems

Installation Notes and Tips

When installing the Four Seasons Expansion Valve 39282, ensure the system is properly evacuated and free of contaminants. Use the two mounting holes to securely fasten the valve in place.
