Bard 5811-018 - Capillary Tube

Bard part number 5811-018 is an OEM capillary tube metering device used in select Bard wall-mounted air conditioners and heat pumps to regulate refrigerant flow and maintain proper system performance. Sized at 0.080 inch ID by 0.140 inch OD with a 16-1/2 inch length, this fixed-orifice capillary is a critical match-to-unit component, so confirm your model and serial number application before ordering to avoid charge and cooling issues caused by an incorrect tube size. As with any sealed-system repair, installation typically involves brazing and proper evacuation, making this a best fit for qualified HVAC service work when restoring factory-correct operation with genuine Bard parts.
