Four Seasons 38729 A/C Expansion Valve

The Four Seasons 38729 is a precision-engineered expansion valve designed to regulate refrigerant flow in automotive air conditioning systems. This critical component meters the high-pressure liquid refrigerant from the receiver-drier or condenser, allowing it to expand into a low-pressure mist before entering the evaporator core.

Key Features:

• Precise refrigerant metering for optimal A/C system performance
• Controls refrigerant superheat to protect compressor from liquid slugging
• Engineered to OE specifications for reliable fit and function
• Constructed with durable materials to withstand thermal cycling and pressure fluctuations
• Direct replacement for failed or malfunctioning original equipment expansion valves

Four Seasons is a trusted name in automotive climate control components, offering professional-grade parts that meet or exceed original equipment standards. This expansion valve helps maintain proper system efficiency and cooling performance when the original valve fails due to contamination, wear, or internal blockage.
