Bard part 5811-042 is an OEM capillary tube used as a fixed metering device to regulate refrigerant flow in select Bard wall-mounted air conditioner and heat pump refrigeration circuits. Built to Bard specifications, this capillary is sized at 0.050 inch ID by 0.114 inch OD and cut to a 50 inch length, helping maintain proper pressure drop and stable system performance when the original tube is restricted, damaged, or has been replaced during sealed-system service. Because capillary sizing is application-specific, match the full part number 5811-042 to your unit model and serial before ordering to ensure correct fit and refrigerant metering.
* Orders less than $50 may incure a minimum order fee.
