Bard 5811-001 - Capillary Tube

The Bard 5811-001 capillary tube is an OEM refrigerant metering component used in Bard wall-mount air conditioners and heat pumps to maintain correct refrigerant flow through the refrigeration circuit. With its specified .050 x .114 sizing and 25 inch length, this fixed-orifice tube helps the system maintain proper pressure drop and stable cooling performance when the original cap tube is restricted, damaged, or leaking. Because capillary sizing is application-specific, match the part number to your unit model and serial data before ordering, and have installation performed by a qualified HVAC technician who can properly recover refrigerant, braze connections, evacuate, and recharge the system to Bard specifications.
