Four Seasons 46639042 A/C Expansion Valve TXV Replacement

The Four Seasons 46639042 is a direct-fit replacement A/C expansion valve (TXV) designed to restore proper refrigerant flow and cooling performance to your vehicle's air conditioning system. Four Seasons is the largest aftermarket mobile climate control parts supplier in the industry, bringing decades of engineering expertise to every component they produce.

Key Features:

• Application-specific calibration — precisely calibrated to provide proper refrigerant flow to the evaporator while restricting and modulating high-pressure liquid, causing a pressure drop that lowers refrigerant temperature for optimal cooling
• OE-matched performance — engineered to meet or exceed original equipment fit, form, and function specifications
• Includes necessary hardware — O-rings, gaskets, and seals included for a complete, leak-free installation
• Precision machined ports — ensures consistent, accurate refrigerant metering across the full operating range
• Quality tested — each valve is validated and inspected to confirm proper superheat setting and maximum operating pressure (MOP) for the specific application
• Durable construction — built with high-quality internal components for long-lasting, trouble-free operation

A worn or failed expansion valve is a common cause of poor A/C performance, including insufficient cooling and compressor issues. Installing the correct, properly calibrated Four Seasons 46639042 replacement valve helps ensure your A/C system operates at peak efficiency and protects other system components from damage caused by improper refrigerant flow.
