Four Seasons 39541 A/C Block Type Expansion Valve

The Four Seasons 39541 is a block-type thermostatic expansion valve (TXV) designed for automotive air conditioning systems. This precision-engineered component regulates refrigerant flow into the evaporator, maintaining optimal cooling performance and system efficiency. Unlike traditional right-angle valves with external capillary tubes, the block-type design offers improved durability and resistance to damage from vibration and environmental factors.

Key Features:

• Block-type design without solenoid for simplified installation
• Engineered to meet or exceed OE specifications for fit, form, and function
• Calibrated for specific tonnage, superheat, and maximum operating pressure (MOP) requirements
• High-quality internal components for long-lasting performance
• Includes application-specific O-rings, gaskets, and seals for proper installation
• Backed by Four Seasons' 50+ years of mobile A/C experience

Four Seasons is the largest aftermarket climate control parts supplier in the industry, with rigorous testing and validation processes ensuring reliable, trouble-free operation. Each expansion valve is precision-manufactured to exact specifications, as improper valve selection or low-quality components can lead to A/C performance issues. This block-type valve represents modern expansion valve technology, offering superior reliability compared to older capillary tube designs.
