Nissens 999918 A/C Expansion Valve

Nissens A/C Expansion Valve for Honda

The Nissens 999918 thermal expansion valve regulates refrigerant flow in the air conditioning system to help maintain stable evaporator performance. Built as an aluminum block-style valve for R134 refrigerant systems, it is a direct-fit service part for select Honda CR-V and Honda Civic applications.

Key Features

• Block-style A/C expansion valve for HVAC refrigerant control
• Aluminum construction for OE-style fit and durability
• Configured for R134 refrigerant systems
• O-rings included for sealing at installation points
• Mounting hardware included where applicable
• OE-matching pressure performance, tightness, opening, set-point setting, and internal finish

Product Details

Nissens 999918 is engineered to meter refrigerant into the evaporator based on system demand, helping the A/C system maintain proper cooling balance. This expansion valve is developed to strict manufacturing standards and validated for pressure performance, leak tightness, opening behavior, set-point accuracy, and internal finish. It cross-references UAC EX10441C and Global Parts Distributors LLC 3411546 for the same application.

Compatible With 2012-2016 Honda CR-V and 2013-2015 Honda Civic. Use this part number 999918 when replacing a worn or restricted valve in these Honda A/C systems.

Common Issues This Part Can Help Resolve

• Weak or inconsistent cabin cooling
• Incorrect refrigerant metering at the evaporator
• A/C performance loss caused by a sticking or restricted valve
• Pressure imbalance in the HVAC refrigerant circuit
• Leak-related service concerns at the valve connection points

Installation Notes and Tips

Verify refrigerant type before installation; this valve is specified for R134 systems. Replace the O-rings during service, inspect the mating surfaces for damage, and confirm the system is clean and properly evacuated before recharging. For best results, match the valve to the vehicle application and confirm the part number 999918 against the original component.

Quality Assurance

Nissens manufactures thermal expansion valves to OE-matching standards and subjects them to comprehensive testing for pressure control, sealing integrity, opening characteristics, set-point accuracy, and internal finish.
