Bard 5811-019 is an OEM capillary tube used as a fixed metering device in select Bard wall-mount air conditioners and heat pumps, helping regulate refrigerant flow and maintain the correct pressure drop across the refrigeration circuit. This cap tube is specified at 0.080 x 0.140 x 18-1/2, so matching the exact size and length is critical to restoring proper system performance and avoiding improper superheat, flooding, or starvation conditions after a sealed-system repair. For best results, confirm the part number against your unit model and serial information and install using proper brazing practices, nitrogen purging, and deep evacuation procedures.
Please call for available options or find replacement parts.
