Bard part number 5811-034 is an OEM capillary tube used as a fixed metering device to regulate refrigerant flow and maintain proper system operating pressures in compatible Bard wall mounted air conditioners and heat pump units. Sized at 0.070 inch ID by 0.125 inch OD and 25 inches long, this component is typically selected by specific model and serial number because cap tube sizing directly affects capacity, superheat, and overall reliability. If you are troubleshooting poor cooling, icing, or incorrect pressures after a sealed system repair, replacing the capillary tube with the correct Bard factory part helps restore designed performance and fit without field guessing.
