The Bard 5811-021 capillary tube is an OEM refrigerant metering component used in Bard wall-mounted air conditioners and related packaged equipment to help control refrigerant flow through the refrigeration circuit. With a 0.080 inch internal diameter, 0.140 inch outside diameter, and 32-1/2 inch length, this fixed-orifice tube is sized to maintain proper pressure drop and stable system operation when replacing a restricted, damaged, or incorrectly sized cap tube. For best results, match the part number exactly and confirm system model and refrigerant application before ordering, since capillary sizing is critical to cooling performance and compressor protection.
