The Source1 2919387014 is a refrigerant orifice designed for use in HVAC refrigeration systems. This precision-machined component plays a critical role in controlling refrigerant flow through the system. The orifice has a bore diameter of 0.055 inches, which determines the flow rate of refrigerant moving from the high-pressure side to the low-pressure side of the system. Proper orifice sizing is essential for system efficiency, correct superheat levels, and reliable compressor protection. HVAC technicians rely on orifice fittings like this one when servicing, repairing, or replacing metering devices in residential and light commercial air conditioning and heat pump equipment. The Source1 brand supplies OEM-quality replacement parts built to meet the same standards as the original factory components, making this a dependable choice for service calls and system maintenance. Refrigerant orifices are commonly found in fixed-orifice metering systems, which are simpler and more durable than thermostatic expansion valves. In these systems, the orifice is located at the inlet of the indoor coil and meters liquid refrigerant into the evaporator. Selecting the correct orifice diameter is critical because an orifice that is too large or too small will cause the system to run inefficiently, leading to poor cooling performance, elevated energy costs, or equipment damage. This part is compatible with York and other systems that use the same orifice specification. HVAC service technicians and contractors should verify the orifice diameter against the equipment manufacturer specifications before installation. Using a matched OEM replacement like the Source1 2919387014 helps ensure the system performs as designed and meets its rated efficiency ratings.
The Source1 2919387014 refrigerant orifice delivers reliable, factory-matched refrigerant flow control for HVAC systems requiring a 0.055 inch metering orifice. It is a straightforward, dependable replacement part for service technicians maintaining York and compatible air conditioning or heat pump equipment.
