Detailed Product Description

The Four Seasons Expansion Valve 39042 is a thermostatic expansion valve (Txv) designed to regulate refrigerant flow in automotive air conditioning systems. Made from brass, this valve is built to withstand the demands of the HVAC system in Lexus and Toyota vehicles such as the Cressida and LS400. It is engineered to work with R134a refrigerant, which is standard in many modern A/C systems.
