Nissan Skyline R32 Air Conditioning One Way Expansion Valve Assembly

Reliable cabin cooling in your R32 Skyline depends on precise refrigerant flow management, and the factory expansion valve is a common point of failure after decades of use. The Genuine Nissan Air Conditioning One Way Expansion Valve Assembly (also known as the Thermostatic Expansion Valve or TXV) is a direct OEM replacement that regulates refrigerant flow into the evaporator core, controlling pressure drop and temperature for efficient, consistent A/C performance.

This brass-bodied valve assembly comes complete with the proper integrated copper lines for seamless installation in the A/C system near the evaporator (typically in the dash area). It restores accurate metering of refrigerant, preventing common issues such as poor cooling, intermittent performance, icing, or compressor strain that often develop with worn or leaking original units.
