Four Seasons 39233 TXV O-Ring A/C Expansion Valve

The Four Seasons 39233 is a direct-fit replacement thermostatic expansion valve (TXV) featuring an O-ring style connection for automotive air conditioning systems. Designed to regulate refrigerant flow into the evaporator core, this valve precisely controls the amount of refrigerant entering the system to maintain optimal cooling efficiency and prevent compressor damage.

Key Features:

• O-ring style TXV for a leak-free, application-specific fit
• Engineered to meet or exceed OE fit, form, and function requirements
• Application-specific superheat, tonnage, and maximum operating pressure (MOP) calibration
• Includes O-rings, gaskets, and seals for a complete installation
• Tested, validated, and inspected before leaving the manufacturing facility
