Nissens 999312 Air Conditioning Thermal Expansion Valve

The Nissens 999312 is a precision-engineered thermal expansion valve (TXV) designed to regulate refrigerant flow in automotive air conditioning systems. This critical component controls the amount of refrigerant released into the evaporator, maintaining optimal superheat conditions for peak AC performance and efficiency.

Key Features:

• Block-type valve technology for reliable refrigerant metering
• Includes O-rings and mounting hardware for complete installation
• Thorough welding process eliminates gas leakage from the power element
• Outlet and operating pressure tested to OE standards
• Comprehensive validation for pressure performance, tightness, and set-point accuracy
• Specially designed charge formula ensures optimal operation for specific applications
• High-grade materials with inner finish precision and cleanliness

Nissens thermal expansion valves are manufactured to premium quality standards with extensive testing to ensure proper AC system balance, compressor protection, and long-term reliability. The valve maintains required refrigerant parameters to prevent compressor slugging, lubrication issues, and overheating failures.
