71R8475 Red Dot Block Type Expansion Valve – #8 to #12 Hose Connections

The Red Dot 71R8475 Expansion Valve is a block-type A/C expansion valve designed for Freightliner truck HVAC systems that require larger hose sizes and stable refrigerant control. This valve features #8 inlet and #12 outlet connections on both the hose side and evaporator side, making it well-suited for higher-flow applications.

Compatible with R12 and R134a refrigerants, the 71R8475 uses Stat-O-Seal fittings for secure, leak-resistant connections and is commonly referenced by Freightliner OE numbers VCCT1001428N and VCCT1001838L. Its block-style mounting allows for compact installation while maintaining consistent evaporator performance.
