Supco BC46X12 Cap Tube 0.046 ID X 12'

The Supco BC46X12 Cap Tube is flow-control piping that meters refrigerant as it passes through the sealed circuit, creating the pressure difference required for proper operation. Its 0.046-inch internal diameter combined with a 12-foot length determines the volume delivered for the intended application. The tube is routed and connected within the piping arrangement as part of the sealed assembly. Controlled metering ensures balanced pressure in HVAC systems, uniform circulation, effective heat transfer, stable operating features, efficient thermal regulation, and dependable system response under changing conditions.
