Insulated Tube
Our insulated copper tubes utilize high quality insulation material, and are suitable for use in nearly any household or industrial air conditioning system. Each copper tube is manufactured to meet strict international standards, and is available in both double and single insulated types. For different specification needs, customers can request a customized wall thickness, and a length ranging from 3 to 50 meters. Further, each pipe comes with a black or white wrap.
