Source1 2919387005 Refrigerant Orifice 0.073 Inch

Product Description

The Source1 2919387005 is a refrigerant orifice designed for use in residential and light commercial HVAC systems. This precision-machined orifice controls the flow of refrigerant through the system, acting as a fixed metering device between the high-pressure and low-pressure sides of the refrigerant circuit. The orifice bore size of 0.073 inches is a critical dimension that determines how much refrigerant passes through at any given time. Selecting the correct bore size is essential for proper system operation, capacity, and efficiency. Using the wrong orifice size can result in an undercharged or overcharged condition, leading to poor cooling performance, compressor damage, or system failure. HVAC technicians rely on fixed orifice metering devices in systems that do not use a thermostatic expansion valve. These simpler metering systems are common in split-system heat pumps and air conditioners from a wide range of manufacturers. The Source1 brand is the OEM parts line backed by Johnson Controls, making this component a factory-matched replacement for York, Luxaire, Coleman, and other affiliated equipment brands. When replacing a refrigerant orifice, technicians should verify the bore size stamped or labeled on the original part to ensure a like-for-like swap. This 0.073-inch orifice ships in a compact form factor, measuring 2 inches in length, 2 inches in width, and 2 inches in height, with a weight of 0.2 pounds. It is a direct replacement part suited for professional installation. Stock this part for common service calls involving low refrigerant flow, restricted metering devices, or routine system maintenance on compatible York and affiliated brand equipment.
