Detailed Product Description

This A/C expansion valve is made from aluminum, providing strength and resistance to corrosion, essential for long-term HVAC system reliability. The gold color finish adds an additional layer of protection. It features a block type configuration with two mounting holes, allowing for a secure fit in the Dodge Durango's air conditioning system. The valve is designed for use with R134a refrigerant, the standard for many modern vehicles. Both suction and liquid inlet/outlet fittings are female with specific thread diameters (No. 6 and No. 10) and are not threaded, utilizing insert o-ring styles to ensure a tight seal and prevent leaks. The included green O-rings (part numbers 24611 and 24681) are critical for maintaining system integrity.
