Extruded Flexible PTFE Teflon Tube
Made of polytetrafluoroethylene resin, PTFE flexible tubing has the highest working temperature of any fluoropolymer tubing available today. PTFE is widely used as a pressure tubing in general chemical transfer application such as delivery of natural gas and mineral oils, toxic gas
monitoring; and paint, varnish or adhesive delivery lines. This tubing also serves numerous applications in the automotive, electrical and appliance markets. We careful selection of resin type, particle size, temperature and pressure produces smooth and dimensionally stable tubing
In order to consistently ensure the quality of our products, we only use raw materials from leading manufacturers. We are able to produce PTFE tubes in various dimensions with different material properties according to the customer's need and the corresponding requirements
