The Bard 800-0166 cap tube assembly is an OEM refrigerant metering component used in Bard wall mount HVAC systems to regulate and stabilize refrigerant flow into the evaporator, helping the unit maintain proper superheat and reliable cooling performance. When a cap tube becomes restricted, damaged, or contaminated, symptoms often include poor cooling capacity, coil icing, and abnormal operating pressures; replacing it with the correct Bard factory part helps restore the system to its intended operating characteristics and fit. Because cap tube sizing and routing are application specific, confirm the exact part number match to your unit model and serial number before ordering, and use proper refrigerant handling practices during installation.
Please call for available options or find replacement parts.
