Description
The Supco BC3 Capillary Tubing is a control component used in refrigeration for sensing and pressure transfer applications. It features a 0.052″ inner diameter and 0.093″ outer diameter with a 12′ length, designed to transmit temperature or pressure signals between sensing points and control systems. It is commonly placed within the thermostat controls, defrost systems and refrigeration regulators to maintain accurate system response. The tubing supports consistent signal movement within sealed control circuits assisting in the regulation of compressors, evaporators, and related equipment in residential and commercial heating and cooling systems.
