York Expansion Valves & Orifices

Overview

The SOURCE1 2919387017 is a refrigerant orifice fitting designed for use in HVAC and refrigeration systems where precise refrigerant flow control is essential. Manufactured to Aeroquip standards, this orifice fitting delivers consistent, repeatable flow restriction at a 0.075 orifice size, making it a reliable component for technicians working on commercial and residential refrigeration equipment. Refrigerant orifices are critical metering devices in vapor compression refrigeration cycles. They reduce pressure and regulate the flow of liquid refrigerant entering the evaporator, which directly affects system efficiency, capacity, and operating pressures. Selecting the correct orifice size ensures the system runs within design parameters and prevents issues such as flooding, starving, or compressor damage. The 0.075 orifice diameter on this SOURCE1 part is suited for systems requiring precise, low-volume refrigerant metering. HVAC technicians, refrigeration mechanics, and service engineers rely on correctly sized orifice fittings when troubleshooting underperforming systems, replacing worn components, or building new refrigerant circuits. This part is compatible with Aeroquip-style fittings, making it a practical replacement or service component for equipment already using that fitting standard. SOURCE1 is a trusted brand in the HVAC and refrigeration supply industry, producing parts built to meet original equipment specifications. This orifice fitting is compact and…
