Nissens 999375 A/C Expansion Valve Thermal TXV

The Nissens 999375 is a direct-fit air conditioning expansion valve (also known as a thermal expansion valve or TXV) designed to meet or exceed OEM specifications for precise refrigerant flow control in automotive A/C systems.

The expansion valve is a critical component in the vehicle's air conditioning circuit. It regulates the flow of liquid refrigerant entering the evaporator, converting high-pressure liquid refrigerant into a low-pressure mist and enabling efficient heat exchange. A faulty expansion valve can result in poor cooling performance, frost buildup on the evaporator, or compressor damage.

Key Features:
