Expansion Valve Block for Red Dot Units 71R8301

The expansion valve controls the flow of refrigerant into the evaporator. Similar to the carburetor on an engine, the expansion valve prevents flooding and starving of refrigerant supply to the evaporator. The expansion valve is partially responsible for controlling the pressures within the A/C system. **The 78R8301 is one of the most popular expansion valves across a wide variety of OEM and aftermarket A/C systems.** Part Number: 71R8301 Type: Block Refrigerant: R-134A Rating: 1.5 ton Coil fittings: #8 #8 Hose fittings: #6 #10 Special Attribute: 1/4" Through Mounting Holes Special Attribute: Fits Red Dot units E6100, R-1630, R-2300, R-4122, R-5040, R-5045, R-5075, R-6101, R-6840, R-9560, R-9727-2, R-9750, R-9753, R-9755, R-9757, R-9765 Interchange Numbers: 71R8300 0015318 118321C1 12-2012A 1280331C1 14-00301-03 15-50269 15-5490 15-5805 1600 1607 1899035 19115-05422 2045-888 2160074 22-00102 232-8556R 250-6081 250-6801 284238M1 289-4197 31-30901 31-30901-AM 366-4138 3916657 404255
