Description
Universal A/C expansion valve — 3/8″ × 1/2″ flare, 13-1/4″ capillary
A versatile thermal expansion valve (TXV) that meters refrigerant into the evaporator for strong, steady cooling. With 3/8″ flare inlet × 1/2″ flare outlet connections and a 13-1/4″ capillary sensing tube, this universal-fit valve cross-references a wide range of OEM valves.
Universal fit — confirm before ordering. Match your connection sizes and valve style against your original, plus the system’s tonnage/superheat range. Not sure? Call 480-507-2229 and we’ll help you match it.
The valve that controls your cooling
The expansion valve is the metering device between the high-pressure liquid line and the evaporator. It drops the refrigerant’s pressure and controls exactly how much enters the evaporator — the key to efficient, consistent cold air.
The sensing element reads the temperature of the refrigerant leaving the evaporator and feeds it back to the valve, so the valve fine-tunes flow to keep the evaporator fully fed without flooding. A worn or clogged valve shows up as weak cooling, frosting, or air that can’t hold temperature.
Know exactly what you’re ordering
The details that decide whether this part matches your system:
One valve, many applications
Universal fit
A single versatile valve that cross-references many OEM expansion valves — fewer part numbers to stock and source.
Precise metering
Controls exactly how much refrigerant enters the evaporator for strong, steady cooling instead of weak or fluctuating air.
Responsive sensing
Reacts quickly to temperature changes at the evaporator outlet to keep the evaporator fully fed without flooding.
Wide interchange
Cross-references UAC and many OEM and aftermarket brands — see the table below.
Restores cold air
Replacing a failed or clogged expansion valve is one of the most common fixes for A/C that won’t cool.
Built to spec
Manufactured to meet or exceed the original valve’s metering and connection specifications.

Recover refrigerant
Safely recover the system charge before opening any lines.
Fit the valve
Install the valve with fresh O-rings; route and clamp the sensing element correctly and insulate it.
Evacuate & recharge
Replace the drier, pull a deep vacuum, then recharge to spec.
