Nissens 999455 A/C Thermal Expansion Valve

The Nissens 999455 A/C Thermal Expansion Valve is a precision-engineered component designed to regulate refrigerant flow in automotive air conditioning systems. This thermal expansion valve (TXV) serves as a critical metering device that controls the amount of refrigerant released into the evaporator, separating the high-pressure and low-pressure sides of the AC system.

Key Features:

• Manufactured to strict OE quality standards with comprehensive testing and validation
• Thoroughly tested for precise pressure performance, tightness, opening characteristics, and set-point settings
• Specially designed charge formula ensures optimal operation for specific system requirements
• Maintains proper superheat conditions to ensure AC system thermal efficiency and proper balance
• Helps prevent AC compressor failures related to slugging, lubrication issues, and overheating
• Superior inner tightness and cleanliness for reliable, long-term performance
• May include O-rings and mounting hardware when applicable for easier installation

This expansion valve replaces OE number 6461K3 and is engineered to deliver safe, trouble-free operation while maintaining the required refrigerant parameters for your vehicle's air conditioning system. Nissens thermal expansion valves undergo rigorous performance testing to ensure stable function across the full range of refrigerant temperatures and pressures encountered during normal AC cycles.
