Nissens 999796 A/C Thermal Expansion Valve (TXV)

The Nissens 999796 is an OE-quality A/C Thermal Expansion Valve (TXV) engineered for precise refrigerant flow control within the vehicle's air conditioning system. As a critical metering device, the expansion valve regulates the amount of refrigerant released into the evaporator and maintains the separation between the high-pressure and low-pressure sides of the A/C loop.

Key Features:

• Precisely meters refrigerant flow into the evaporator for optimal system efficiency
• Maintains required superheat parameters to protect the A/C compressor from slugging, lubrication failure, and overheating
• Manufactured and tested to OE-matching standards for pressure performance, tightness, opening characteristics, and set-point accuracy
• Includes O-rings and mounting bolts where applicable for a complete, ready-to-install repair
• Validated through comprehensive testing covering pressure output, tightness, opening behavior, and internal finish
• Designed for stable function across the full range of refrigerant temperatures and pressures encountered during normal A/C operation

Nissens draws on over 95 years of thermal engineering expertise to produce expansion valves that deliver reliable, long-service performance. The 999796 is built to restore proper A/C system balance and protect downstream components, making it a dependable choice for professional technicians and DIY installers alike.
