Bard part number 9010-053 is a precision metering orifice sized #33 with a 0.1130 inch diameter, used to control refrigerant flow in compatible Bard wall-mount air conditioners and heat pumps. A properly sized orifice is critical for stable superheat, correct coil feed, and overall system performance, so replacing a worn, restricted, or mismatched piston with the correct Bard OEM part helps restore factory-intended operation. Confirm application by matching the unit model and serial information to the correct refrigerant circuit and tonnage, since orifice sizing is not interchangeable across all Bard configurations, and always follow Bard service procedures when opening the sealed system.
